mph (75 km/h) and a minimum barometric pressure of 1001 mb (hPa; 29.56 inHg). Shortly thereafter, increasing wind shear and decreasing sea surface temperatures caused the system to steadily weaken; at 0000 UTC on September 1, the system deteriorated into a tropical depression, and by 1800 UTC the following afternoon, the system no longer displayed enough organization to be considered a cyclone. The remnant low continued westward and dissipated twelve hours later. Heavy rainfall was reported throughout the state of Sinaloa. A total of 26 neighborhoods were flooded with up to 4.9 ft (1.5 m) of water in the town of Culiacán, while a 14-year-old boy was swept away by a swollen river. Hurricane Henriette A poorly organized tropical wave moved into the eastern Pacific on August 29 and quickly developed into a tropical depression by 0600 UTC the following day. Within an environment of low wind shear, the depression intensified into a tropical storm, acquiring the name Henriette, at 1200 UTC on August 31. Moving west-northwest around a ridge positioned over inland Mexico, the center passed narrowly offshore after producing squally weather along the coastline. The system moved westward while continuing to intensify, becoming a Category 1 hurricane at 0600 UTC on September 4 and subsequently attaining its peak intensity with winds of 85 mph (140 km/h) and a minimum barometric pressure of 972 mb (hPa; 28.71 inHg) six hours later. An approaching upper-level trough caused Henriette to turn northwest later that day, moving it ashore near San José del Cabo, Mexico at 2100 UTC as a minimal hurricane. After crossing Baja California Sur, Henriette weakened to a tropical storm and made a second landfall near Guaymas, Mexico. The system moved inland and quickly weakened, dissipating by 1200 UTC on September 6. The hardest hit city by Henriette was Acapulco, where heavy rains led to rockslides and mudslides that killed six. In Sonora, the hurricane damaged thousands of structures and killed four, two of whom off the coast. Farther northwest, a woman died while attempting to surf waves off the coast of Baja California Sur. Heavy rains stranded many cars while causing rivers to overflow, flooding communities. Damage totaled to $275 million (2007 MXN; $25 million). Hurricane Ivo A tropical wave moved off the western coast of Africa on September 1 and continued westward until reaching the eastern Pacific fifteen days later. A broad area of low pressure formed
