A long, narrow band of moisture that dumps massive amounts of rain—is currently drenching San Francisco and the Bay Area. Forecasters say the heaviest rain will continue through Tuesday night into early Wednesday, with some areas seeing several inches of rainfall.
What’s Happening Right Now?
- Flood Watches are in effect across San Francisco, the North Bay, and the Central Coast until early Wednesday.
- Roads are already flooding in some low-lying areas, and emergency officials warn that urban streets, creeks, and drainage systems may not be able to handle the water.
- Strong wind gusts of up to 50 mph could knock down trees and power lines, leading to outages.
The National Weather Service has urged residents to avoid unnecessary travel, as roads could become impassable due to standing water and mudslides.
 NEXT THREAT: TEMPERATURES PLUMMET AS FREEZE WARNING ISSUED
Just as the rain clears, a wave of cold air will push into the region, bringing some of the lowest temperatures of the season. A Frost Advisory is in effect for the North Bay Interior Valleys from 11 PM Tuesday to 9 AM Wednesday, with some areas dropping to 32°F or lower overnight.
Who’s at Risk?
- People without proper heating or shelter should prepare for a bitterly cold night.
- Pets, plants, and exposed pipes could be at risk—residents are advised to cover sensitive vegetation and ensure pets stay warm indoors.
If you’re planning to head out early Wednesday morning, be prepared for icy conditions and an uncomfortable chill that could last for days.
 WHEN DOES THE STORM END? WEEKEND FORECAST
Once the storm moves out, San Francisco will see cooler, drier conditions heading into the weekend. The rain will clear by Thursday, but temperatures will remain chilly, with highs only reaching the mid-50s.
Here’s What to Expect:
- Thursday: Breezy and cool, with scattered showers lingering.
- Friday: Sunshine returns, but morning temperatures will stay cold in the low 40s.
- Saturday & Sunday: Mostly sunny but cool, with highs in the mid-50s and lows in the 40s.
While this particular storm will pass, forecasters aren’t ruling out another strong system next week, so residents should stay prepared for more potential flooding and storms later this month.

-  Prepare for power outages – Charge your devices and have flashlights ready.
-  Dress in layers – The temperature drop will be significant, especially at night.
- Check on elderly neighbors and pets – Cold weather can be especially dangerous for vulnerable populations.
