Cyclone: Hurricane Kathleen
Date it affected AZ: September 11, 1976
Affected Arizona as...: Tropical Storm (passed just west of Yuma, AZ; dissipated over northern Arizona)
Although Kathleen only briefly achieved hurricane status, she is known in Arizona as an extensive wind producer because she moved so quickly north and thus had little time to weaken before racing north into Nevada. Yuma, AZ, which was on the windy right side of the storm, recorded sustained winds of 57 mph and gusts to 76 mph before the power went out at the NWS field office. There were no flood reports in southern Arizona (the heaviest rains stayed west of Kathleen's track in California. However the sheer size of Kathleen and the intensity of the winds in Yuma suggest that tropical storm-force winds probably extended as far east as western Pima County, AZ, and possibly extended as far north as Lake Havasu, AZ.
