, 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 360 miles (579 km) southeast of Acapulco and was designated as Tropical Depression Eleven-E.

 coast bringing heavy rains. With continued strong convection, Henriette maintained its strengthening and was predicted to reach hurricane strength. However, despite the low wind shear and apparent warm waters. Henriette did not strengthen as expected.

. Henriette turned westward and away from the Pacific coast of Mexico late on September 1 as the subtropical ridge built westward over northern Mexico.

Henriette continued to improve in structure and with the formation of a distinct eye feature, reached hurricane strength on September 4 as it turned north-northwestward toward the Baja California peninsula, ahead of a mid-latitude trough approaching the west coast of the United States. The hurricane reached its peak intensity of 85 mph (135  km/h) that morning while centered about 75 miles (120 km)south-southeast of Cabo San Lucas

The center of Henriette made landfall just east of Cabo San Lucas on the afternoon of September 4 with maximum winds near 80 mi/h (130  km/h). It was over land for only about six hours before emerging into the Sea of Cortez. The brief interaction with land caused a slight weakening, but Henriette remained a Category 1 hurricane for most of that day. The next day it made final landfall near Guaymas

. Henriette weakened quickly over land and dissipated over the mountains of northwestern Mexico early on September 6. The remnants of Tropical Storm Henriette continued to track across west Texas and southeastern New Mexico as it was being absorbed by a cold front moving through New Mexico. The flow of moisture from originating from these remnants, moderate instability, and marginal shear contributed to flash flooding and severe thunderstorms.

Preparations

The formation of Henriette was not anticipated well in NHC Tropical Weather Outlooks. The incipient system was first mentioned only about 31 hours before it became a tropical depression, and the potential for the formation of a depression was explicitly stated beginning only about 13 hours prior to genesis.

Impact

Henriette struck hardest in the resort town of Acapulco. Though the storm never passed closer than 70 mi (112.7 km) to the town, heavy rains along the coast saturated the ground, leading to mudslides. Six people were reported dead as a result of rockslides in two suburban neighborhoods of the city and in the port itself. Three were killed by a huge rock hitting their house, and the other three were killed when their dwellings partially collapsed. In addition, flooding from the overflowing of the River La Sabana, led to the evacuation of at least one hundred families from around the river by the Consejo Estatal de Proteccion Civil.

Jorge Antonio Pacheco Albert, Director of Civil Protection for the Port of Acapulco, reported that approximately 800 were injured during the passage of Henriette along the coast and that 337 people relocated to temporary shelters. In Michoacán
