Light overnight rain in Bay Area but more on the way

Big storm on the way after light overnight rainfall in Bay Area.

Overnight rain throughout the Bay Area was minimal, but a major cold front moving in on Sunday is expected to bring heavy showers, strong winds, high surf, thunderstorms and potential flooding, according to the National Weather Service.

With the exceptions of San Jose and Danville that had .01 amount of rain and Mt. Diablo that had .05, the majority of the Bay Area did not have any measurable rainfall or just had traces  between 10 p.m. Saturday and 4 a.m. Sunday.

But conditions will continue to deteriorate through Sunday afternoon and evening with heavy rain expected all night and another low-pressure system Monday that could also cause problems, the weather service said.

Brayden Murdock, an NWS meteorologist, said Sunday “it’s not the worst so far this season, but we still have concerns. Some things could be very impactful.

“This isn’t going to be as aggressive as we saw two weeks ago, but there will be some issues this evening to tomorrow” with moderate to heavy rains across the area.

He said the forecast through Wednesday is for  1 1/2 to 2 1/2 inches of rain for the area, but higher peaks and some other areas could  get 3 to 5 inches.

There currently is a wind advisory for southwest winds  25 to 35 mph with gusts up to 50 mph, the NWS said.

A flood watch scheduled to begin at 10 a.m. Sunday  will remain in effect through 10 a.m. Wednesday and a small craft advisory, which started at 9 a.m. Sunday, will last until 3 a.m. Tuesday.

In the Greater Lake Tahoe Area, a winter storm warning that could impact travel remains in effect from 4 p.m. Sunday to 10 a.m. Wednesday.

The NWS in Reno said a period of heavy snow, that could reach 2 to 4 feet above 7,000 feet, will arrive Sunday evening  and continue through Monday morning  and then  periods of moderate to heavy snow will follow Monday afternoon through early Wednesday.
