Hurricane Henriette

Hurricane Henriette was a minimal Category 1 hurricane that affected portions of Mexico in late August and early September 2007. The storm, which caused nine fatalities, formed from an area of disturbed weather on August 30, 2007, and became a tropical storm the next day. The cyclone moved parallel to the Mexican Pacific coast, but its proximity to the shore resulted in heavy rainfall over land. The most affected city was Acapulco, Guerrero, where six people were killed by landslides, and where over 100 families had to be evacuated after the La Sabana River flooded. Henriette then turned north and headed towards the Baja California peninsula, and became a Category 1 hurricane on the Saffir-Simpson Hurricane Scale. Henriette made its first landfall east of Cabo San Lucas at peak intensity, causing the death of one woman due to high surf. Hurricane Henriette then emerged over the Gulf of California, and made its second landfall near Guaymas. After causing heavy rains and killing four individuals in Sonora, the storm dissipated over the Sierra Madre Occidental and its remnants went on to cause flooding in New Mexico and Texas. Damage totaled about $275 million (2007 MXN, $25 million 2007 USD). It hit Mexico on the same day Hurricane Felix hit Nicaragua, only one of two occurrences in which a North Atlantic hurricane and a Pacific hurricane made landfall on the same day. Meteorological history Henriette originated from a tropical wave that departed the west coast of Africa on August 20, 2007. The wave produced some convection while in the Caribbean Sea but reached Central America on August 28 before any significant development could occur. Early on August 30, the area of low pressure, now 400 miles (640 km) south-southeast 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. By 0600 UTC that day the system became a tropical depression about southeast of Acapulco and was designated as Tropical Depression Eleven-E.
