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.
