No tropical storm has made landfall in Southern California since Sept. 25, 1939, according to the National Weather Service. The watch warned of numerous potential threats to life and property including extreme flooding, mudslides and tornados.
Hurricane officials said the storm could bring heavy rainfall to the Southwestern United States that could dump 3 to 6 inches in parts with isolated amounts of up to 10 inches to portions of southern California and southern Nevada, hitting large desert areas unaccustomed to much rain.
Storms don’t usually hit Southern California because prevailing winds usually push them either due west into open ocean or northeastward into Mexico and other parts of the U.S. Southwest, said Masters and Massachusetts Institute of Technology hurricane professor Kerry Emanuel.
