Hurricane Norbert is the strongest storm thus far in the 2008 Pacific hurricane season. Norbert was the fifteenth tropical cyclone, fourteenth named storm, seventh hurricane of the season, and second major hurricane of the season. Norbert has claimed at least three lives after making its final landfall in the Mexican state of Sonora.[1]
Meterological history
The origins of Norbert were from an area of disturbed weather that formed near the Gulf of Tehuantepec on September 28.[2] Drifting westward off the coast of Mexico, the system initially consisted of a broad low pressure area and an area of disorganized convection.[3] It slowly organized for several days, and by early on October 4 the system developed enough organized convection to be classified as Tropical Depression Fifteen; at that point, it was located about 230 miles (370 km) south of Acapulco. The depression was located over an area of warm water temperatures and moderate vertical wind shear, and as such was forecast to intensify gradually.[4]
About six hours after forming, the circulation of the depression became exposed from the deep convection, due to the wind shear. At the same time, two tropical cyclone forecast models predicted the tropical cyclogenesis of a larger disturbance to the southeast of the depression.[5] One model predicted the new cyclone to absorb the depression, although most other models forecast for the depression to remain the dominant system.[6] By early on October 5, deep convection developed and organized around the center of the depression, and satellite intensity estimates using the Dvorak technique suggested tropical storm force winds; as a result, the National Hurricane Center (NHC) upgraded the depression to Tropical Storm Norbert, about 245 mi (394 km) south of Zihuatanejo.[7] Norbert was upgraded to a hurricane on October 6.[8] On October 7, it reached Category 2 intensity on the Saffir-Simpson Hurricane Scale.[9] Overnight, an eye appeared on infrared satellites, indicated that Norbert was intensifying and was upgraded to a major hurricane respectively. Continuing to strengthen, it reached Category 4 that afternoon, before weakening into a Category 1 by October 9, but restrengthened into a minimal major hurricane on October 11, and made landfall that day as a Category 2.[10]
Naming
When Tropical Depression Fifteen-E strengthened into Tropical Storm Norbert late on October 4, it marked the first time worldwide that a storm had been named Norbert in 18 years; the last time a tropical cyclone in any basin was given the name was in the 1990 Pacific hurricane season, although it was also previously used in the 1984 season.[11]
Preparations
A hurricane warning was issued on October 10 for parts of central Baja California from Puerto San Andresito southward to Agua Blanca, and they extended around the peninsula from La Paz to Loreto. The warnings also went on the mainland west coast from Topolobampo to Guaymas. Hurricane watches were issued from Agua Blanca to Cabo San Lucas, and extended around the Baja peninsula to La Paz, and these same areas were also under tropical storm warnings as well. Tropical storm warnings also extended from Loreto northward to Mulege on the eastern side of the peninsula.
Impact
Hurricane Norbert struck Mexico's Baja California peninsula on Saturday with torrential rains and winds of up to 155 km/h. Strong winds bent palm trees along coastal areas. Some streets were in knee-deep water in the town of Puerto San Carlos. Norbert was ripping off roofs, knocking down trees and left one person missing and more than 20,000 homes without electricity, local authorities say. Some 2850 people were housed in temporary shelters. Forty per cent of homes were totally or partially damaged on the islands of Margarita and Magdalena, mainly having lost their roofs, said a report from state protection services. La Paz international airport suspended its activities at midday local time Saturday, but the tourist resort of Los Cabos remained open. Hotel reservations were down by around 40 per cent mainly in Los Cabos and Loreto, local tourism officials said. [12]
Norbert was a Category 2 hurricane at landfall, which made Norbert the first October hurricane to strike the Baja California peninsula since Hurricane Pauline forty years prior, and Norbert was the stronger of the two.
