00:00And as we look at the big picture across the west, satellite and radar together first,
00:04you can see soaking rain in Northern California, but this is a band of heavy rain and wind
00:09moving through the Bay Area.
00:10Now entering the Central Valley is a bigger concern on the local scale.
00:14You can see there's been a little swarm of severe thunderstorm warnings over the past
00:18few hours between San Francisco proper and Monterey Bay.
00:22So as we zoom in one more step, at the moment there are no current severe thunderstorm warnings
00:27in effect with this, but we're not far from that.
00:29We recently had one just expire southwest of San Jose.
00:32You can see still some high reflectivity.
00:34This fine line.
00:35It's moving through Vallejo.
00:36It's approaching Sacramento.
00:37Look out for the wind to increase and the rain as well as this marches through San Jose,
00:42highly populated areas into Pittsburgh, California and other areas just east of the Bay Area
00:47as well.
00:48So again, we've got some issues approaching the Interstate 5.
00:52Wind is a big concern even separate from that squall line, but again, we may see a couple
00:57more severe thunderstorm warnings issued then into Southern California.
01:00There are areas of their flood watches because from San Diego up into Oceanside and Orange
01:05County up into Los Angeles and coastal parts of Ventura County, we are looking at flood
01:10watches.
01:11Some of those areas at especially high risk.
01:13If you've had a recent wildfire in the past couple of years, especially places like Altadena
01:18and Pacific Palisades from just two months ago, we are looking at a more significant
01:22risk of mudslides, debris flows and so forth.
01:25But overnight tonight, the rain expands more in the way of mountain snow as well.
01:29Impacts in Southern California, debris flows near the burn scar areas, snow levels all
01:33the way down to 3,000 feet, heavy snow above 5,000 feet in elevation, one to two inches
01:38of rain very likely for most areas.
01:41The west-facing foothills will see two to four inches of rain, but the snow is a huge
01:46story as well.
01:47And by the numbers, some of these areas with winter storm warnings are looking at two to
01:51four feet of snow, Donner Pass, Bear Valley, parts of the Yosemite National Park area and
01:57also ten plus inches for others farther south.
