2011: Strong offshore winds hit the region.
In San Bernardino gusts hit 70 mph with sustained winds of 49 mph.
A few trucks were overturned on I-15 and I-210.
Power lines were downed near San Bernardino.
2011: Powerful winds and low snow levels accompanied an upper level low that was centered over the Colorado River Valley.
In Pahrump, Nevada downslope winds took place for several hours in the morning off the Spring Mountains and produced gusts as high as 94 mph that downed numerous trees, tore shingles off of roofs and blew over a radio tower.
One woman was injured when a carport was torn down by the winds and fell on her.
The rare northeast component of the winds was likely a key factor in contributing to at least 20 trees being downed at the trailhead to Mt. Whitney at Whitney Portal, California.
Snow levels dropped to 3,000 feet with this low and snow fell briefly but did not accumulate in Summerlin.
In the higher portions of the Anthem neighborhood of Henderson, very light snow accumulations took place on shrubs, car tops and other colder surfaces.
The Las Vegas Ski and Snowboard Resort on Mt. Charleston measured 39 inches of snow at the 9200 foot level.
2011: A Mono Wind event took place along the crest of the Sierra Nevada, adjacent foothills, and parts of the San Joaquin Valley, including the north side of Fresno.
Damage in the Fresno area was estimated at $2 million due to down power lines, trees, and property damage.
Strong northeast winds felled numerous trees in Fresno and in Yosemite National Park, and power outages affected at least several thousand customers due to down power poles.
Daytime high temperatures in locations where strong winds occurred rose about 15 to 20 degrees from the previous day as these winds were dry and allowed the air to heat as it traveled down the slopes of the Sierra and foothills.
2007: Heavy rain from cutoff low with a tropical connection produced up to 6" of rain at Palomar Mountain and Forest Falls on 11.30 and on this day.
A debris flow (including large trees) over the Poomacha Burn area buried a house in mud, and caused serious damage to several vehicles and highway 76.
The flow was estimated at 15 feet high and 150 to 200 feet wide.
1986: Extremely high tides on this day and on 12.2 arrived at area beaches.
High tides were 7.7 feet at San Diego.
Minor flooding occurred at La Jolla Shores' parking lot and there were a few beach closures.
On 12.1 minor flooding (4" of sea water) occurred along Pacific Coast Highway in Huntington Beach from rising tides and prompted lane closures.
1982: A big storm that started on 11.30 and ended on this day brought widespread record rains and strong winds that knocked out power to 1.6 million homes.
1973: Palo Alto received 1.88" of rain.
1973: 22" of snow fell at Glenbrook, NV (east shore Lake Tahoe).
1973: A funnel cloud was sighted north of the Fresno Air Terminal.
