Hurricane Hilary was a large and intense Pacific hurricane in August 2023 that brought torrential rainfall and gusty winds to the Pacific Coast of Mexico along the Baja California peninsula, and the Southwestern United States, resulting in widespread flooding and mudslides to the region. The hurricane was the eighth named storm, sixth hurricane, and fourth major hurricane of the active and highly destructive 2023 Pacific hurricane season. Hilary originated from a tropical wave south of Mexico on August 16, and strengthened into a hurricane a day later while paralleling the southwest coast of Mexico. The system underwent rapid intensification, reaching maximum sustained winds of 140 mph (220 km/h) and a central pressure of 940 mbar (27.76 inHg) on August 18, making it a Category 4 on the Saffir-Simpson scale. After environmental conditions became unfavorable, Hilary weakened as it approached land, making landfall on August 20 as a tropical storm in San Quintín along the western Baja California peninsula. Hilary became a post-tropical cyclone over land, before being absorbed into a new non-tropical low-pressure area early on August 21. Category 4 hurricane: peak winds of 140 mph (120 knots), lowest pressure 940 mb. August 16 – August 20, 2023. Landfall: August 20 at 60 mph, 29.7°N 115.6°W. Accumulated cyclone energy: 13.2.
