March 15, 2023 (San Diego) -- The latest atmospheric river to drench our region dumped several inches of rainfall in many San Diego County areas over the two days ending Wednesday at 5:45 p.m.
Palomar had 5.78 inches of precipitation. In East County, the Mesa Grande reservation had 3.82 inches and Lake Cuyamaca got 3.56 inches.Julian received 2.44 inches and nearby Pine Hills had 3.09 inches. Descanso had 2.43 inches. Many other communities received between 1.6 and 2 inches including La Mesa, Santee, Ramona, and Pine Valley.
Though this is heavy precipitation for San Diego County, some areas elsewhere in California have set all-time records for deep snow levels. Cal Trans warns motorists to avoid some areas due to avalanche dangers, and some avalanches have already occurred.
Topping the list is Mammoth, with a whopping 780 inches of snow currently at the summit --- a staggering 65 feet, according to the Mammoth Winter report. Snow is so heavy that ski resorts are having to dig out ski lifts buried under snowdrifts.
Mono County Tourism tweeted a photo from Mammoth Lakes with a warning stating, “All roads in and out of Mono County are currently closed. Avalanche danger is extreme.” Avalanches have struck other California mountain areas as well as Lake Tahoe in recent days.
The wet weather has caused significant damage in some parts of the county. State Route 78 is closed westbound at College due to a massive sinkhole, Caltrans reports. In Julians, some residents are experiencing leaking roofs and other damage. Winds blew down trees across the County, blocking roadways. Geologist Pat Abbott has warned of signs of an impending cliff collapse in Torrey Pines, not far from where a Blacks Beach bluff recently collapsed.
Warmer, drier weather is forecast for Thursday, with a chance of showers returning over the weekend, according to the National Weather Service. Widespread rain and snow at higher elevations are expected next Tuesday and Wednesday.
