2006: A thunderstorm dropped heavy rain along the Elsinore Convergence Zone. Significant mudslides (debris flows) occurred in north San Jacinto, trapping 19 vehicles. A few homes and businesses were also damaged.
2003: Strong thunderstorms produced 1.75 inch hail in Joshua Tree and Twentynine Palms. 0.75 inch hail fell in the Julian area. A tornado in Joshua Tree and Yucca Valley caused extensive damage ($25,000) to one residence and minor damage to 11 other residences (no injuries).
1997: Hurricane Linda became the strongest storm recorded in the eastern Pacific with winds estimated at 180 mph and gusts to 218 mph. For a time it threatened to come ashore in California as a tropical storm, but the storm turned away, impacting the region with added moisture for showers and thunderstorms. This occurred during the strong El Niño of 1997-98. 2.5 inch per hour rain rates and golf ball size hail were recorded at Forest Falls. Disastrous flooding and debris flows occurred at Forest Falls, totaling $3.2 million in damage, two houses were destroyed and 77 damaged. Car-size boulders and a wall of mud 150 feet wide and 15 feet tall were reported. Flooding damage also occurred at Oak Glen.
1991: A thunderstorm complex produced golf ball sized hail across parts of the San Bernardino Mountains. The Big Bear Lake area reported hail up to 2.5 inches deep.
1984: A tropical air mass lasting two weeks and high sea surface temperatures led to record minimum temperature records set each day except one at San Diego starting on this day and ending on 9.19. Low temperatures ranged from 73° to the highest minimum of all time of 78° on 9.9 and 9.17. The high was 100° on 9.8.
1976: Five tornadoes were reported around El Mirage, west of Victorville, and one near Mt. Baldy during a period that started on this day and ended on 9.6. Property damage resulted.
1963: Tropical storm Jen-Kath hit Baja California just south of Ensenada. The resulting tropical depression staggered across the border into Southern California producing daily record rainfall for most stations on this day.
1939: The remnants of a hurricane tracked northeastward across northern Baja California into southwest Arizona starting on this day and ending on 9.6. Up to seven inches of rain fell on the mountains and deserts. Blythe received more rain than would normally fall in a year and Imperial received more rain than would normally fall in two years. Four tropical cyclones would impact Southern California during the month of September 1939, an unprecedented occurrence. 1.21 inches fell in San Diego. Floods through eastern canyons inundated Thermal with three feet of water. Extensive damage occurred in Mecca.
