On this day in…
2000: Thunderstorms hit the desert with 1.5 inches of rain in only 45 minutes and wind gusts to 61 mph at Borrego Springs. Flash flooding resulted, with mud in homes and damaged roads in the Borrego Springs area. Flash floods, mud and debris covered roads from Yucca Valley to Palm Springs and Oasis.
1972: Hurricane Hyacinth moved as far west as 125 West before recurving to the northeast. The remnants made landfall between Los Angeles and San Diego on the 9.3 with winds of 25 mph and rainfall of up to one inch in the mountains from this day to 9.6. This tropical cyclone holds the distinction of traveling the farthest west before recurving and making landfall in Southern California. This occurred during the El Niño of 1972-73. Only 0.44 inch was measured in San Diego.
1951: A hurricane moving north northwestward just off the west coast of Baja California moved northeastward into northern Baja California and dissipated. Moisture from this tropical cyclone resulted in rainfall of two to five inches in the mountains and deserts starting on 8.27 and ending on this day. Many roads were washed out in the Imperial Valley, but otherwise no major damage occurred. This occurred during the El Niño of 1951-52.
