[californiadisasters] On This Date In California Weather History (October 11)



2015: Unseasonable high pressure and warm ocean waters led to very warm October days
and the warmest October nights on record from this day through 10/15.
In San Diego, five out of the six highest October minimum temperatures on record occurred.
The highest minimum temperature in any October was 76° on this day and again on 10/13.
This is only two degrees off the highest minimum temperature for any time of year!
(Onlyseven nights in history recorded 77° or 78°, all of which occurred during September, meaning these October nights were warmer than any night in July or August in San Diego).
On this day the highest minimum temperature in October was also recorded in Chula Vista (73°, only three degrees off all-time highest), Oceanside Harbor (74°, only two degrees off all-time
highest), and El Cajon (tied 69°).
On 10/13 Santa Ana recorded 78°, the highest October minimum temperature on record.
The top six warmest October nights on the Chula Vista record occurred this month, and the top five in El Cajon occurred this month.

2012:
A waterspout was observed about 200 yards off the coast of Carlsbad.
Numerous pilot reports were received of waterspouts off the coast in the vicinity of North Island and Imperial Beach.
Other waterspouts were seen off the coast of Orange County.
No landfall or damage was reported.

2008: Snow flurries fell in Summerlin, NV (suburb of Las Vegas).
This is the earliest known occurrence of snow
flurries in the Las Vegas Valley.

1991: Probable downburst winds in Kings County between Hanford and Corcoran, spawning an F0 tornado.

1973: The morning low temperature at Reno, NV was 21° F.

1969: Strong jetstream winds mixed down to the surface as powerful Mono Winds at night blowing off shutters on the Goat Mountain lookout.

1963: Los Gatos received 1.49" of rain.

1957: Heavy rain hit San Bernardino.
Rainfall of 0.5" occurred during 10 minutes at Del Rosa Ranger Station (a 40 year occurrence).
Total was 1.37" at the site from 10.11 to 10.14.
The rains eased the fire threat, but burn areas from fires the previous August led to debris flows into the northern San Bernardino area.
Tons of mud and debris were deposited in dozens of homes and yards from Little Mountain to Del Rosa.

1924: An early season cold snap gripped Southern California from this day to 10.13, setting numerous daily minimum temperature records.

1899: Record low maximum temperature for the month of October, 53° F, in Fresno is recorded.
