Cyclone: Hurricane Katrina
Date it affected AZ: September 1-2, 1967
Affected Arizona as...: Tropical Depression (southwest Arizona)
 
Katrina was one of only two tropical systems in the satellite era to move up the entire Gulf of California. She made several landfalls over Baja California before crossing the coast for the last time near the mouth of the Gulf of California. Weakened by the mountains on either side of the Gulf, Katrina quickly degenerated into a tropical depression by the time she reached Yuma, but then made a right turn and passed northeast across central Arizona before finally dissipating as she approached the Mogollon Rim. Between 2 and 4 inches of rain fell over southwest Arizona, with 4.78 inches in Wellton, AZ, and 2.16 inches in Ajo, AZ. This same storm was far worse over Baja California, where sustained winds near 100 mph destroyed half the town of San Felipe, Baja Norte, Mexico.
