Hurricane Olivia was a powerful and destructive Category 4 hurricane, that brought damaging floods to California and Utah during September 1982. Olivia was the twenty-fourth tropical cyclone, eighteenth named storm, ninth hurricane, and fourth major hurricane of the active 1982 Pacific hurricane season. The storm was first noted as a tropical depression from a ship report off the southern coast of Mexico. Olivia then steadily intensified before becoming a Category 4 hurricane, and reaching its peak intensity with 1-minute sustained winds of around 145 mph (230 km/h), at 18:00 UTC on September 21. The hurricane then rapidly weakened as it passed west of mainland Mexico, before being last noted to the west of California on September 25, as a surface trough.
Moisture from Olivia was pulled across the Western United States and Southwestern Canada by a strong southwesterly flow. This resulted in several inches of rainfall, which caused damaging flash flooding and mudslides, namely in Utah. Large amounts of crops were destroyed by the storm in California. Overall, damage from Olivia is estimated to be around $475 million (1982 USD), with 3 fatalities.
