Hurricane Juliette was a powerful Pacific hurricane that struck Mexico in September 2001. A long-lived tropical cyclone, Juliette originated from a tropical wave that exited western Africa, the same wave that earlier spawned Atlantic Tropical Depression Nine near Nicaragua on September 19. Two days later, a new tropical depression developed offshore Guatemala, which became Hurricane Juliette by September 22 as it rapidly intensified off western Mexico. On September 24 it strengthened into a Category 4 hurricane on the Saffir-Simpson scale, only to weaken due to an eyewall replacement cycle, then re-intensified a day later to attain maximum sustained winds of 230 km/h (145 mph), with a minimum barometric pressure of 923 mbar (27.3 inHg). Juliette weakened as it moved toward the Baja California peninsula, producing hurricane-force winds and torrential rainfall across Baja California Sur. On September 30 after the hurricane had weakened, Juliette made landfall near San Carlos as a minimal chia. After drifting across the Gulf of California, Juliette dissipated on October 3.

During its path across the Pacific, Juliette affected much of the Pacific coast of Mexico, killing 13 people from Chiapas to the Baja California peninsula. The strongest winds and heaviest rainfall occurred in Baja California Sur, with wind gusts of 174 km/h (108 mph), and a precipitation total of 1,011 mm (39.80 in) recorded at Santiago. Damage in the country reached over Mex$1.755 billion (US$188 million)^{[nb 1]}, of which the worst effects were in the state of Sonora. There, the rains over three days equaled the average annual precipitation, which resulted in flooding and landslides. The hurricane also killed a sailor off the coast of Acapulco. Thunderstorms extended into the southwestern United States, knocking down power lines near Palm Springs.
