[edit] Storm history
Henriette originated from a tropical wave that moved off the coast of central America on August 28. Early on August 30, 2007, the area of low pressure, now 600 kilometers (400 miles) southsoutheast of Acapulco, Mexico started to gain clusters of strong convection. By the afternoon of August 30 the system continued to show strong convection and had developed a broad but well defined area of low to mid level cyclonic turning.[1]
At 1800 UTC UTC, the area of disturbed weather was designated as Tropical Depression Eleven-E. Convection continued, but the cyclone encountered extensive easterly to north-easterly wind shear which stinted the strengthening of the storm through out its life. [2] The depression moved north west, parallel with the west coast of Mexico, due a mid and upper-level steering ridge.
On August 31, it strengthened to become Tropical Storm Henriette[3], as it continued to move along the Mexican coast, bringing heavy rains. Henriette continued to strengthen due to low wind shear and high SSTs, and NHC forecasts indicated that Henriette would become a hurricane. However, despite favorable conditions, Henriette remained a tropical storm. This is believed a result of its close proximity to land and colder waters brought to the surface by Henriette's slow movement. It maintained its strength as it moved away from Jalisco towards Baja California, and reached hurricane strength on September 4 as conditions become more favorable for development. The hurricane reached its peak intensity of 75 kt that morning while centered about 75 NM south-southeast of Cabo San Lucas.
Hurricane Henriette made landfall on the tip of the Baja California peninsula near San José del Cabo on September 4[4]. It remained over land for six hours before emerging into the Sea of Cortez, still at hurricane strength[5]. The next day it made final landfall near Guaymas in the state of Sonora[6], and dissipated soon after.

[edit] Mexico
The first advisory was issued on August 30 at 2100 UTC whilst Henriette was still a Tropical Depression. A tropical storm warning stretched from De Chacahua westward to Acapulco with a Tropical storm watch stretching west of Acapulco to Zihuatanejo.
On August 31, despite the storm moving parallel to the coast of the states of Oaxaca, Guerrero and Michoacan, the National Weather Service in Mexico issued a warning from Lagoons Chacagua, Oaxaca to Cabo Corrientes, Jalisco . Similarly, they appealed to the public to use extra precautions before the possible coming of moderate to heavy rains, strong winds and high waves in the south and southwest coasts of Mexico.
On 3 September, the Interior Minister Francisco Ramirez Acuna reported that it had imposed a warning in 17 states in Mexico since August 30, for the mobilization of Civil Protection in preventing their respective entity before the impending predicted trajectory and closeness that had in previous days had Henriette in costs and their effect on Mexican national territory.
On September 4, the National Weather Service declared zone warning from Mulege, Baja California Sur to Cabo San Lucas, and the latter to the port of San Andresito. [5] In La Paz, the Municipal Directorate of Civil Protection reported that in a first stage will be opened 13 temporary shelters in the city and is expected to evacuate more than 2,000 people living in high-risk areas. It was also unveiled that are available a total of 40 temporary shelters. [10] Furthermore, the Education Department reported that the state be suspended classes in the municipalities of La Paz and Los Cabos from 4 September until the passage of meteor in the peninsula of Baja California.
According to forecaster Rhome of the National Hurricane Center, watches or warnings may be required starting late on September 2.[7]
[edit] Impact
Henriette brought heavy rain to the area around Acapulco. Those rains caused a mudslide that has killed six people. Three were killed by a huge rock hitting their house, and the other three were killed when their dwelling partially collapsed.[8]
In Baja California Sur, the threat of the hurricane prompted the evacuations of about 300 people.[9] Two fishermen were reported killed off the Sonora coast.[10]
