The 2009 Pacific hurricane season officially began on May 15 in the Eastern Pacific and June 1 in the Central Pacific; it ended on November 30th. Within this period, usually make the most tropical storms because only at this time appropriate conditions exist, such as a warm ocean , moist air and little wind shear to the formation of tropical cyclones to allow. All storms that form north of the equator and east of 180 ° W belong to this basin. Storms that form further west are no longer called hurricanes , but typhoons .

Although the East Pacific Basin is the second most active tropical cyclone generation area in the world after the West Pacific, most storms do not threaten any land, as they mostly steer out into the open ocean . Only a few storms take a curve to the east or northeast and then mainly threaten the Mexican coast.

Tropical cyclones in the Atlantic Ocean see the article: Atlantic hurricane season 2009 .

On May 21, 2009, NOAA announced its seasonal forecast for the hurricane season in the Eastern and Central Pacific Oceans. Accordingly, a below-average season was expected in the Eastern Pacific with 13 to 18 named storms, 6 to 10 of which were hurricanes, of which two to five should achieve severe hurricane status.

The forecast was based on the dissolution of La Niña in April 2009. Water surface temperatures near the equator were almost normal. In addition, the El Niño is assumed to be formed later in the season . Depending on the strength of the El Niño, meteorologists were unsure whether this would have any effect on general activity in the basin. Due to the low activity cycle that began in 1995, El Niño would bring the season to a maximum of or slightly above average.

A slightly below average season was also expected for the central Pacific. According to this, three to five tropical cyclones should migrate to the area between 140 and 180 degrees west longitude or form there.

Season overview

The situation on August 12th: From left to right the dissolving systems Maka and Felicia, the low nine-E and the just developing Hurricane Guillermo can be seen.

2009 is the first year since 1999 that no named storm has formed in May. Since 1999, there have been one or two such storms in May every year. These ten years make up the longest uninterrupted period of time that this has been the case since records began. On average, May storms form in the eastern Pacific Ocean one year over the other, so the absence of a storm in May is normal. The first tropical system of the year was a short-lived tropical depression that encountered Sinaloa , Mexico; it is the only known system that did this in June. When the NHC declared Tropical Depression Two-E to be Tropical Storm Andres on June 23, it was the second latest date for the first storm. Only in 1969 did the first storm develop later, when Ava became a tropical storm on July 1st. However, in its summary of tropical weather events for August, the NHC found that August 2009, with seven named storms, was the most active month in 41 years since eight named storms occurred in the eastern Pacific in August of the 1968 hurricane season .

Lana, the sixth tropical low pressure system of the season, was only the fourth known tropical cyclone to emerge as a low pressure area in the eastern Pacific Basin and was named in the central Pacific Ocean; the other three were Lala (1984), Iniki, and Li (1994). Lana was the first tropical storm in the Central Pacific since Kika 2008 and also the first tropical cyclone to migrate from the eastern to the central Pacific Ocean since Flossie (2007). While Felicia was still active, Tropical Depression One-C formed, making the 2009 season the first hurricane season since the 2002 Pacific hurricane season in which two tropical systems were active simultaneously in the Central Pacific.

Storms

Tropical depression Eins-E

Tropical depression
Duration	June 18 - June 20
intensity	30 kn (55 km / h ) (1 minute) , 1003 hPa

A weather disturbance existed off the southwest coast of Mexico on June 15 that slowly migrated west-northwest, creating a depression as it gained organization. The system organized itself better, and on June 18, the National Hurricane Center classified the first tropical depression of the 2009 Pacific hurricane season, about 595 km south-southwest of Mazatlán , Mexico . Deep atmospheric convection existed in the southern part of the system, in the northern part there was sometimes no convective activity at all. A trough over Baja California led the system to move northward. The system remained disorganized for most of its existence due to wind shear . One-E dissolves when it landed on June 20th.

On June 19, 62 mm of precipitation fell near Mazatlán, causing flooding on the city's streets. The wind uprooted trees and knocked down power lines. Landslides and rockfalls caused several traffic accidents on the main roads.

Hurricane Andres

Category 1 hurricane
Duration	June 21st - June 24th
intensity	70 kn (130 km / h ) (1 minute) , 984 hPa

Late on June 21st, around 335 km south of Zihuatanejo, a tropical depression formed, which six hours later intensified into a tropical storm and was named "Andres". At around 2:00 p.m. PDT on June 23, Andres was declared a hurricane, with the intensification to the hurricane occurring earlier. Andres, however, weakened again slightly, so that the NHC downgraded the system to a tropical storm again around 8 p.m. local time on June 23. The system continued to move in a more north-westerly direction. Strong wind shear and dry air had their effects on the system, which weakened quickly, so the NHC issued its final warnings on Andres on June 24th.

Heavy rains associated with Andres caused severe flooding in the Acapulco region . 200 residents had to be evacuated from their homes. A fisherman drowned in a lagoon northwest of town when his boat capsized.

Tropical storm Blanca

Tropical storm
Duration	July 6th - July 9th
intensity	45 kn (85 km / h ) (1 minute) , 998 hPa

On July 6, a weather disturbance about 675 km south-southwest of the tip of Baja California was declared a tropical storm by the National Hurricane Center without having previously been classified as a tropical depression. "Blanca" had deep convection and possibly one eye . The storm intensified further during the day. Extensive rain bands developed and around the center the wind reached a constant speed of 75 km / h. Some of the predictive models assumed it would intensify rapidly before the storm entered an obstructive environment; However, these predictions did not come true, so that on July 8th, Blanca was downgraded to the tropical low pressure area and one day later to the residual low. About 1,600 km west-northwest of the southern tip of Lower California, the system disintegrated on July 10th.

Unusually for July, the remnants of the system brought rainfall to southern and central California on July 11th.

Hurricane Carlos

Category 2 hurricane
Duration	July 10th - July 16th
intensity	90 kn (165 km / h ) (1 minute) , 971 hPa

On July 9, a weather disruption associated with showers and thunderstorms organized about 1,450 km south of the tip of Lower California into a low pressure center that was classified as the fourth tropical low pressure area in the eastern Pacific Ocean on early July 10. At around 2:00 pm PDT, the system intensified into Tropical Storm "Carlos". On July 11, the National Hurricane Center rated Carlos as a minimal hurricane.

Carlos trained a small eye that could be seen on satellite images. But overnight, for some inexplicable reason, the hurricane lost its intensity and the eye disappeared. The deep convection was confined to a small region around the circulation center and the size of the system decreased, so that Carlos was graduated into a tropical storm. This weakening trend continued on July 13th before Carlos was able to reverse the trend. On July 14th an eye developed again and Carlos intensified again into a hurricane,

The hurricane reached its greatest strength on July 15 at 9:00 a.m. UTC with wind speeds of 90 knots as a Category 2 hurricane. From then on the intensity steadily decreased until on July 16 the NHC issued the last warning about the system.

Tropical storm Dolores

Tropical storm
Duration	July 15 - July 16
intensity	50 kn (95 km / h ) (1 minute) , 997 hPa

On July 14, a weather disruption south of Baja California gained sufficient organization to be classified as the fifth tropical depression. On the morning of July 15, the system was classified as a tropical storm and was named "Dolores" by the National Hurricane Center. Dolores formed band structures and reached its greatest strength in the early morning of July 16 with wind speeds of 35 knots. In the course of the day the system lost strength and weakened to a tropical depression. Because the deep convection was lost overnight, the NHC declared the system to be residual low on July 17 at 8:00 a.m. PDT. This moved north for a few days before it dissolved near the west coast of California on July 20.

Tropical storm Lana

Tropical storm
Duration	July 30th - August 3rd
intensity	55 kn (100 km / h ) (1 minute) , 995 hPa

On July 30, a fault developed on the western edge of the eastern Pacific to become the sixth tropical depression of the season. Six hours later, the system intensified, now west of the 140th degree of western longitude, to a tropical storm and was named "Lana". The storm began with the formation of an eye, but southerly wind shear caused a slight disorganization of the system due to an altitude trough. Lana nevertheless reached its greatest intensity on August 1st with wind speeds of 55 knots. The storm eased significantly, although wind speeds still hit 45 knots for the next few days. Late on August 2, Lana weakened to a tropical depression and disintegrated to a residual low on August 3, about 930 km southwest of Honolulu , Hawaii and 660 km east of Johnston Island , giving the Central Pacific Hurricane Center the final warning on Lana issued; in the course of August 4, the residual low disappeared completely.

Tropical storm Enrique

Tropical storm
Duration	August 3 - August 7
intensity	55 kn (100 km / h ) (1 minute) , 994 hPa

The tropical storm "Enrique" developed from an extensive low pressure area with the center several hundred kilometers south-southwest of Baja California Sur into a tropical system. The center with the circulation was in an area that was favorable for further development. The depression moved in a west-northwest direction as it responded to a high pressure ridge north of the system. A second low pressure area, which was located about nine degrees of longitude further west, also had the disposition to develop into a tropical system and to influence the tropical low pressure area Seven-E. Late on August 3rd, the system intensified into a tropical storm and was named "Enrique". Enrique intensified briefly and reached its greatest strength on August 4th with wind speeds of 50 km. The impact of nearby Hurricane Felicia weakened the system in the late evening. Enrique maintained this intensity until early August 6, but was then downgraded from the NHC to a tropical depression. On August 7th, the system issued the final warning to Enrique.

Hurricane Felicia

Category 4 hurricane
Duration	August 3 - August 11
intensity	125 kn (230 km / h ) (1 minute) , 935 hPa

Late on August 3, a tropical low pressure area formed around 160 km southwest of the southern tip of Lower California and, after a few hours earlier to the east, the Tropical Low Pressure Area Seven-E was classified as Tropical Low Pressure Area Eight-E. The system intensified rapidly and was declared a tropical storm three hours later and was named "Felicia".

Felicia quickly developed an eye. The warm water in the area of ​​the predicted train track was held responsible for this intensification. On the afternoon of August 4, Felicia achieved hurricane status, which in the evening had already reached Category 2 on the Saffir-Simpson Hurricane Wind Scale. On August 5, the NHC upgraded Felicia to a Category 3 hurricane, making Felicia one of the major hurricane of the season. During the course of the day, Felicia intensified rapidly into a Category 4 hurricane with a maximum wind speed of around 230 km / h. Felicia became the strongest Pacific hurricane since Daniel during the 2006 Pacific hurricane season .

On August 8th, Felicia crossed the border to the Central Pacific Basin and steadily weakened as it approached Hawaii , first to a tropical storm and finally to a tropical depression. Storm warnings were issued for the Big Island, Maui and Oahu on August 9 , but were lifted two days later when Felicia was downgraded to a residual low.

Tropical Depression Nine-E

Tropical depression
Duration	August 9th - August 12th
intensity	30 kn (55 km / h ) (1 minute) , 1006 hPa

Tropical Depression Nine-E developed on August 9th from a small depression west-southwest of Baja California. On August 12th, the tropical depression Nine-E dissolved.

Tropical storm Maka

Tropical storm
Duration	August 11th - August 12th
intensity	35 kn (65 km / h ) (1 minute) , 1007 hPa

Tropical Depression One-C evolved from a depression southwest of Kauai on August 11th . A few hours later, "Maka" was upgraded to a tropical storm as the second system of the season in the CPHC's area of ​​responsibility. The next day the storm decreased in intensity. This weakening came as a surprise and was explained by the meteorologists with previously unexpected wind shear, so that Honolulu issued the last warning about the system. The remaining low Makas bobbed over the date line into the western Pacific Ocean and developed there again into a tropical low pressure area.

Hurricane Guillermo

Category 3 hurricane
Duration	August 12th - August 19th
intensity	110 kn (205 km / h ) (1 minute) , 954 hPa

The Tropical Storm Guillermo was formed on August 12 about 700 miles southwest of Baja California of a large low-pressure system out. The system developed good vortex and convection and eventually turned into a tropical storm in the afternoon. On August 14, Guillermo intensified into a Category 1 hurricane. During the day, Guillermo intensified rapidly, so at 11:30 p.m. PDT the NHC determined that Guillermo had developed into a major hurricane. Over the next few days the system moved further west. After reaching 140 degrees of longitude, the Central Pacific Hurricane Center determined that Guillermo's Eye was no longer visible due to the effects of west-southwest shear winds. The next day, Guillermo was also downgraded to a tropical storm. On August 19th, Guillermo broke up.

Tropical storm Hilda

Tropical storm
Duration	August 22nd - August 28th
intensity	55 kn (100 km / h ) (1 minute) , 999 hPa

The eleventh tropical low pressure area of ​​the season was created on August 22nd on the western edge of the National Hurricane Center's area of ​​responsibility. It was upgraded to Tropical Storm Hilda for a few hours and crossed 140 degrees west longitude on August 23. Hilda moved further west for the next few days, with the storm initially intensifying only slowly due to eastern shear winds. However, the system pulls along the south side of a ridge, so that the outflow in the northern semicircle is obstructed. The CPHC initially predicted that Hilda would intensify into a hurricane, but dry air made the storm to create and hindered further development. This trend lasted through August 25th and 26th before the storm began to weaken. On August 28th, the CPHC issued the final warning to Hilda, at this point it had already fallen to a residual low.

Tropical storm Ignacio

Tropical storm
Duration	August 24th - August 27th
intensity	45 kn (85 km / h ) (1 minute) , 999 hPa

The Tropical Depression Twelve-E formed late on August 24th about 1060 km southwest of the southern tip of Lower California. Although the convection within the rain bands on the western semicircle of the system decreased somewhat, the system organized itself better and was declared a tropical storm a few hours later. "Ignacio" was not particularly well organized, however, and a number of smaller vortices were arranged around its center of circulation. Ignacio failed to intensify significantly and, after getting into an area with water temperatures below 26 ° C, weakened to a tropical low pressure area on August 27, which lost its tropical properties that same day.

Hurricane Jimena

Category 4 hurricane
Duration	August 29th - September 4th
intensity	135 kn (250 km / h ) (1 minute) , 931 hPa

A tropical wave emerged in the western Caribbean , crossed Central America and slowly developed in the Pacific Ocean. In the early morning of August 29, the wave intensified about 350 km south of Acapulco to the Tropical Depression Thirteen-E and soon after to a tropical storm. This was named "Jimena" and intensified on the same day to a category 2 hurricane on the Saffir-Simpson hurricane wind scale . Jimena made a little eye. The next day, the hurricane intensified into a major hurricane, the third of the season. The intensification continued and on August 30th the relatively small hurricane reached Category 4.

On August 31, Jimena presumably underwent cyclical re-formation of the eyewalls, which caused the hurricane to lose some of its force. Its direction of movement turned from the northwest to a more northerly orbit through a subtropical ridge over northwest Mexico and a subtropical to extra-tropical cyclone west of Baja California. There he unexpectedly gained strength again and was at least at the top end of Category 4 on the Saffir-Simpson scale. It is possible that the hurricane even reached Category 5. On the way to Mexico's Baja California peninsula, however, the system weakened again to a Category 3 hurricane. Although still above the sea, Jimena began to affect the mainland with heavy rain and high waves around the tourist area around Los Cabos in the south of the peninsula. On September 2, Jimena continued to move north along the coast as it continued to weaken to Category 2. In the afternoon, local time, the hurricane center near San Aventura , around 100 kilometers south of Santa Rosalía , crossed the coastline and hit land at a speed of between 140 and 150 km / h. Overland, Jimena continued to weaken. Since the system had not shown deep convection for more than twelve hours on September 4th, it was declared a residual low on that day.

If Jimena had hit Baja California at its original strength, Category 4 or 5, it would have been the strongest tropical storm there on record. One of the worst hurricanes in the past to hit the peninsula directly was Kiko, a level 3 hurricane , in 1989. Hurricane Lane (2006, category 3) and Kenna (2002, category 5) hit neighboring regions on mainland Mexico. Jimena himself went ashore near Puerto San Carlos with wind speeds of up to 110 km / h. He destroyed houses and cut off some villages from the outside world. A fisherman was reported missing. Otherwise there were no personal injuries to complain about.

Tropical Depression Two-C

Tropical depression
Duration	August 29th - August 30th (West of 180 ° West Longitude)
intensity	30 kn (55 km / h ) (1 minute) , 1007 hPa

Tropical Depression Zwei-C emerged on August 29 at 3:00 am UTC from a small weather disturbance southwest of Kauai . The system moved westward and crossed the dateline in the early hours of August 30 and came under the jurisdiction of the Japan Meteorological Agency . There the system could not intensify any further and dissolved a few hours later.

Tropical storm Kevin

Tropical storm
Duration	August 29th - August 31st
intensity	45 kn (85 km / h ) (1 minute) , 1000 hPa

The 14th tropical low pressure area of ​​the season was formed on August 29 from a weather disturbance around 1,600 km southwest of the southern tip of Lower California, west of the developing Hurricane Jimena. The depression was not very well developed, but intensified for the seventh named storm in the eastern Pacific in August. "Kevin" failed to intensify and an adverse environment took its toll. On August 30, Kevin continuously lost his strength, so that the NHC downgraded Kevin to a tropical depression on August 31. It broke up the same day.

Hurricane Linda

Category 1 hurricane
Duration	September 7th - September 11th
intensity	70 kn (130 km / h ) (1 minute) , 985 hPa

The Tropical Depression Fifteen-E was classified on September 7th. It developed from a low pressure area located about 1770 km west-southwest of the seats of Lower California. After the constant winds reached 95 km / h during the day, the system was upgraded to a tropical storm and was given the name "Linda". Linda slowly intensified into a Category 1 hurricane by September 10th and peaked with sustained winds of 140 km / h on September 10th. The hurricane then quickly lost strength, so that by midday on September 11th it was barely classified as a tropical storm. During the course of the day, Linda weakened first to a tropical depression and then to a residual low, so that the NHC no longer issued any further warnings about Linda. Linda's remains weakened and fell into a shallow trough on September 15; they were finally absorbed by a front system on September 10th.

Tropical storm Marty

Tropical storm
Duration	September 16 - September 19
intensity	40 kn (75 km / h ) (1 minute) , 1002 hPa

The tropical low pressure area Sixteen-E formed on September 16 about 550 km south-southwest of Cabo San Lucas and intensified within a few hours to a tropical storm, which the NHC named "Marty". Marty reached its greatest intensity on September 17th with a central air pressure of 1001 hPa and sustained wind speeds of 75 km / h, before slowly weakening over the next two days. On September 19, the NHC issued the final warning on Marty. The remaining low disappeared completely by September 24th.

Tropical storm Nora

Tropical storm
Duration	September 22nd - September 25th
intensity	50 kn (95 km / h ) (1 minute) , 997 hPa

On September 21, an extensive low pressure area formed about 1,440 km west-southwest of the southern tip of Lower California. This weather disruption slowly began to organize and intensified into a tropical depression late on September 22nd. A few hours later the low pressure area had developed into a tropical storm and was given the name "Nora". On this day, Nora reached the greatest strength with sustained wind speeds of 90 km, before the system weakened again because of a nearby trough. Early on September 25th, the NHC issued the final warning to Nora.

Tropical storm Olaf

Tropical storm
Duration	October 1st - October 3rd
intensity	40 kn (75 km / h ) (1 minute) , 996 hPa

The tropical low pressure area Eighteen-E formed on October 1st from an extensive low pressure area and rapidly intensified to the tropical storm "Olaf". As it moved north and northeast towards Baja California, the storm came over cooler water and under the influence of wind shear, so that it initially weakened to a low pressure area on October 3. A few hours later, the NHC stopped the warnings because Olaf fell into a residual low.

In Baja California Sur , torrential rain flooded low-lying communities, especially around La Paz . Heavy rainfall was also recorded in parts of Sonora and Sinaloa.

Tropical storm Patricia

Tropical storm
Duration	October 11th - October 15th
intensity	50 kn (95 km / h ) (1 minute) , 996 hPa

On October 11th, a disturbance formed a tropical depression. It organized itself more and more, until finally the NHC upgraded the low pressure area to a tropical storm with the name "Patricia". On October 14th, Patricia hit the southern tip of Lower California and immediately weakened again to a low pressure area.

Hurricane Rick

Category 5 hurricane
Duration	October 15 - October 21
intensity	155 kn (285 km / h ) (1 minute) , 906 hPa

With its intensity "Rick" is after Linda in 1997 the second strongest hurricane, which was recorded in the North-East Pacific. Rick was born from a tropical wave that turned into a tropical depression on October 15th. The system migrated in a west-northwest direction and entered a region that made explosive intensification possible. Shortly after being classified as a tropical low pressure area of ​​Twenty-E, the system was upgraded to a tropical storm. With its intensity, Rick is the second strongest hurricane recorded in the North-East Pacific after Linda in 1997. Less than 18 hours later, Rick was already hurricane strength. After a brief period of stagnation, the NHC upgraded the cyclone to the highest category 5 in just 36 hours on October 17th. Rick was the first Category 5 hurricane in the Eastern Pacific since Hurricane Kenna in the 2002 hurricane season .

In the early hours of October 18, Hurricane Rick reached its greatest intensity with sustained wind speeds of 285 km / h and a central air pressure of 906 hPa, but shortly afterwards increasing wind shear and drier air masses weakened the cyclone. On October 19, Rick had weakened into a Category 3 hurricane. Rick turned in a more northerly direction, threatening the southern tip of Baja California. During this period, Rick continued to lose strength and was graduated to a tropical storm on October 20th. At that point in time the storm was already strongly asymmetrical, most of the convection had shifted northeast. Rick made it overland at Mazatlan the next day with winds of 95 km / h. Within twelve hours of landing, Rick broke up.

Three people were killed in Mexico as a result of the storm. The damage caused by the hurricane was minor.

Hurricane Neki

Category 3 hurricane
Duration	October 18 - October 27
intensity	110 kn (205 km / h ) (1 minute) , 950 hPa

On October 18 at 11:00 a.m. HST (1:00 a.m. UTC), tropical depression Drei-C formed. It was around 1,100 km south of Hawaii at the time. The formation of the system was unusual because it formed from a fault in the Inertropical Coinvergence Zone (ITCZ). This lay south of Hawaii for several days and developed an organized circulation on October 19th. In the morning of the next day, Drei-C intensified into Tropical Storm "Neki". This slowly gained strength and reached hurricane strength on the afternoon of October 20th. The next day, Neki reached Category 2 on the Saffir-Simpson Hurricane Wind Scale. After a period of slow intensification, Neki reached Category 3, becoming the first major hurricane to emerge in the Central Pacific since Hurricane Ioke formed during the 2006 hurricane season . After Neki had reached the greatest intensity with wind speeds of 205 km / h and a central air pressure of 950 hPa, the hurricane slowly weakened. The last time Neki reached hurricane strength was on October 22nd, one day later Neki's strength was only a tropical storm. As a tropical storm, Neki lasted three more days before the system weakened to a tropical depression on October 26th. In the early hours of October 27th, Neki disintegrated into a surface trough, which was blowing away across the northern Pacific at a forward speed of almost 60 km / h and drooping clouds that were in a long circulating motion.

Neki moved over the Papahānaumokuākea Marine National Monument near the French Frigate Shoals on October 23, but did no damage there. The hurricane was the first tropical cyclone to impact the Hawaiian Islands since Hurricane Iniki in the 1992 hurricane season . For two nature reserves the effects were more severe; Round Island lost land and Disappearing Island was completely washed away.

The table opposite shows the ACE for every storm this year. The ACE describes the energy of a tropical storm by multiplying the strength of a storm with the duration, i.e. long-lasting storms as well as strong storms have a high ACE value. Traditionally, the NOAA only recorded named storms with wind speeds of over 34 knots (63 km / h), but not in phases in which they were classified as subtropical.

The values ​​in brackets relate to the areas west of the 140th degree of longitude, i.e. the central Pacific, those without brackets to the areas east of it.
