The Sierra Avalanche Center has warned there is a “high avalanche danger” at all elevations of the Sierra Nevada mountains because of heavy snowfall that has closed several ski resorts. The authorities advised against travel in the area, warning of intense snowfall rates and gale force winds.
NWS meteorologist Brett Albright said the storm dumped as much as 101.6 mm (4 inches) of rain in some places. "Today was very intense. It’s not a normal event. It was definitely a culmination of the perfect circumstances: We had a very intense atmospheric river with a lot of moisture and an area of lift in the atmosphere right over coastal Los Angeles and Orange counties. It forced all of that moisture out.”
“It’s not often we see higher rainfall totals on the coast than in the mountains,” Albright said.
LA Times said rockslides closed roads in Malibu and other coastal mountain areas. In Isla Vista, a cliff and a patio collapsed into the ocean. Rescuers had to evacuate 15 to 20 residents of ocean-front apartment units, a spokesperson for the County of Santa Barbara said. A homeless encampment off of the Pacific Coast Highway in the Harbor City neighborhood was submerged in several feet of water. Sunday afternoon, both the 110 Freeway in Carson and the 710 Freeway in Long Beach were shutdown due to extreme flooding that left cars stranded like islands in a lake. Rockslides closed roads in Malibu and other coastal mountain areas.
Firefighters in San Bernardino County staged a dramatic swift-water rescue of a couple whose pickup truck was trapped in surging water west of the Cajon Pass.
