The 2017 Pacific hurricane season got off to an early start in 2017; tropical storm Adrian formed late on May 9th. Its formation is the earliest known tropical storm in the eastern Pacific Ocean . The annual hurricane season officially begins here on May 15th and in the Central Pacific on June 1st, and by general agreement it ends on November 30th. It is during this time that most tropical storms usually form , as only then do suitable conditions exist: a warm ocean , moist air and little wind shear . All storms that form north of the equator and east of 180 degrees west are classified as hurricanes; Storms that form further west are called typhoons .

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

Storms

Tropical storm Adrian

Duration May 9 - active
intensity 40 kn (75 km / h ) (1 minute) , 1004 hPa

On May 5, the National Hurricane Center (NHC) indicated that a low pressure area would form south of Mexico within the next few days and that it would subsequently develop possibly tropical characteristics. A broad cyclonic circulation began to develop late on May 7th, and at 23:00 UTC the system organized itself into the first tropical depression of the year. The formation of the low pressure area about 875 km southeast of Salina Cruz , Mexico was the earliest formation of a tropical low pressure area in the eastern Pacific Ocean since reliable weather records began. (The previously earliest system in the Eastern Pacific was the formation of Hurricane Alma on May 12, 1990.) Six hours later, the system intensified into a tropical storm and was named Adrian .

Tropical storm Beatriz

Duration May 31st - June 2nd
intensity 40 kn (75 km / h ) (1 minute) , 1001 hPa

A tropical wave appeared off the west coast of Africa on May 18 and entered the eastern Pacific about a week later, where steady organization resulted in the formation of a tropical depression on May 31 at 12:00 UTC. Embedded in a south-westerly current around a large high-altitude trough over northern Mexico, the low-pressure area moved steadily to the northeast in a favorable environment and intensified on June 1 at 06:00 UTC to form tropical storm Beatriz. After reaching peak wind speeds of 75 km / h (45 mph), the tropical storm hit land on June 2 at around 00:00 UTC about 40 kilometers west of Puerto Ángel . The mountainous terrain of Mexico quickly disturbed Beatrice, so that the tropical storm finally dispersed twelve hours later.

In the state of Oaxaca , flights from Bahías de Huatulco International Airport were canceled and schools were closed until at least June 3. Dozens of roads have been made impassable due to mudslides and flooding. Numerous landslides led to considerable disruptions in the entire federal territory, in particular by blocking the federal highway 200 in many areas. A landslide in San Marcial Ozolotepec killed two girls and buried several houses, while another in San Carlos Yautepec killed a woman. A total of seven people were killed on June 4 - five in Oaxaca and two in Tehuantepec. Less than two weeks after Beatrice, tropical storm Calvin hit similar areas in Mexico, causing additional damage. The combined damage from the two systems reached at least 70 million pesos ($ 3.9 million) in Oaxaca.
