[californiadisasters] On This Date In CA Weather History (September 24)
On This Date In California Weather History....
1997: Heavy rain and thunderstorms developed on this day and ended on 9.26.
Moisture came from the remnants of Hurricane Nora, which had moved up the Gulf of California and weakened over Yuma, AZ, giving that city more rainfall in three hours than for a normal entire season.
Rainfall totals were 5.50 inches at Mt. San Jacinto, 4.70 inches Mt. Laguna, 4.41 inches Mt. San Gorgonio, three to four inches at several other locations in mountains, 3.07 inches in Twentynine Palms, 1.5 to two inches at Coachella and Borrego Valleys, 2.88 inches in Hemet, and one to two inches in many inland areas.
Flooding occurred in Palm Springs, Borrego Springs, and Spring Valley.
Traffic deaths also resulted.
1986: Early season storm brought snow at Lodgepole and Grant Grove with storm totals of 4 inches at both.
1986: Unseasonable rainfall hit San Diego County on this day and on 9.25: 1.04 inches fell in San Diego, 5.14 inches in Palomar Mountain, 2.07 inches in Julian, 1.88 inches in Mt. Laguna, 1.61 inches in Lemon Grove, 1.58 inches in Pt. Loma, 1.57 inches in Vista, and 1.47 inches at SDSU.
Flooding occurred in low roadways in Mission Valley.
The Angels' home game at Anaheim Stadium against the Cleveland Indians was rained out.
1982: The remnants of Hurricane Olivia recurved northeastward across Southern California with rainfall up to four inches in the mountains starting on this day and ending on 9.26. This occurred during the strong El Niño of 1982-83.
1976: A thunderstorm dropped four inches of rain in three hours in Borrego Valley. Only 1.2 inches fell at the Anza Borrego Desert State Park headquarters. Damage and erosion to fields, property, and the airport resulted.
1963: Thunderstorms hit the San Bernardino Mountains and high desert around Barstow, producing flash flooding east of Barstow.
1945: It was 26° in Idyllwild, the lowest temperature on record for September.
This also occurred the previous day on 9.23.1945, on 9.20.1965, and on 9.21.1968.
1939: A thunderstorm on this day dropped 6.45 inches in six hours at Indio.
This preceded "El Cordonazo" or "The Lash of St. Francis", an actual tropical storm.
For the entire storm, which started on this day and ended on 9.26, four inches of rain fell across the deserts and mountains as a dying tropical cyclone moved across Baja California into southwestern Arizona.
This was the second tropical cyclone to impact California during the busy month of September 1939.
A strong El Niño may have contributed to the activity.
The tropical storm produced 50 mph winds over the ocean and estimated seas of 40 feet.
48 died from sinking boats and harbors were damaged.
Californians were generally unprepared and were alerted to their vulnerability to tropical storms.
In response, the weather bureau established a forecast office for Southern California, which began operations in February of 1940.
1887: Fresno reached 104 degrees for a high temperature.
This is the oldest high temperature record still standing in the record books for Fresno.
