Unrelenting rain is expected to persist in the Bay Area as two back-to-back storm systems close in on the region this week, accompanied by up to 60 mph wind gusts, possible thunderstorms, landslides and flooding.

The slew of warnings and advisories comes as an atmospheric river moves out of the region after slamming the Golden State over the weekend. Another storm is approaching California from the northwest and is expected to bring heavy rain and mountain snow to much of the state beginning on Wednesday night and lasting through the end of the week.

The Climate Prediction Center, a division of the National Oceanic and Atmospheric Administration (NOAA), released its long-range forecast for December 2025 through February 2026 on Thursday. The outlook tells two different stories: a cold, wet winter for some states versus a hot, dry season for others.

Light rain and snow led to wet roads for the Valley and Foothills on Thursday morning, with chain controls possible in the Sierra. Thursday is a KCRA 3 weather Impact Day because of the potential for minor delays during the morning hours.

Another storm system is expected to bring rain to an already soaked Southern California for two days starting Thursday afternoon, bringing snow to local mountains, forecasters say.

In Southern California, the latest atmospheric river shattered daily rainfall records set during a massive 1965 storm. Some major Bay Area cities have also received a substantial amount of rain in November, such as San Jose, Santa Rosa and San Francisco, which received between 4 and 8 inches of rain, according to the National Weather Service.

Light rain and snow led to wet roads for the Valley and Foothills on Thursday morning, with chain controls currently in the Sierra.

Santa Barbara, parts of Ventura county and more saw more than several inches of rain in recent days. Is it going to continue raining?
