Cyclone: Tropical Storm Hyacinth
Date it affected AZ: August 21, 1968
Affected Arizona as...: Tropical Depression (extreme southeast Arizona)
 
Satellite imagery and surface observations indicated that the decaying circulation center from Tropical Storm Hyacinth probably made it into southeast Arizona before dissipating over Cochise County. Because Hyacinth was never a strong storm, the decaying depression probably would have dissipated before arriving in southeast Arizona had it not been for its rapid northward movement at over 20 mph. The rapid movement kept rainfalls limited with spotty one to two inch amounts over Cochise County. Y Lightning Ranch south of Sierra Vista, AZ reported 2.30 inches of rain.
