If you woke up today looking for a tornado warning San Francisco today map, you’re probably either staring at a weirdly dark sky or you saw a frantic post on social media. Honestly, it’s usually the latter. San Francisco isn't exactly "Tornado Alley," but when the wind starts howling through the Salesforce Tower, people start panicking.
Let’s get the big question out of the way immediately. As of Thursday, January 15, 2026, there is no active tornado warning for the city of San Francisco.
The radar is actually looking pretty quiet on the vortex front. Instead of worrying about a twister picking up your car on Lombard Street, you should probably be looking at the Beach Hazards Statement issued by the National Weather Service (NWS) Bay Area. We’ve got some nasty sneaker waves and rip currents hitting the Pacific coast until 9 PM tonight. Basically, the ocean is much more dangerous than the sky today.
Why the Confusion About a Tornado Warning San Francisco Today Map?
It’s kinda weird how these rumors start. Usually, someone sees a "hook echo" on a weather app or a localized cell of intense rain and assumes the worst. Or, they’re remembering the wild weather from a couple of years back.
Remember December 2024? That was the time a genuine tornado warning actually woke people up on a Saturday morning. It felt like a glitch in the matrix. San Francisco residents aren't used to those loud, buzzing EAS alerts for anything other than earthquakes or Amber Alerts.

When you look at a live weather map today, you’ll see a high-pressure ridge hanging out off the coast. This is actually doing the opposite of creating tornadoes. It’s trapping air. That’s why we have a Spare the Air alert in effect. The air is stagnant. It’s "gross" air, not "spinning" air.
What the Current Map Actually Shows
If you pull up the NWS interactive map right now, here is what you’re actually seeing:
- Green/Yellow Zones: Mostly coastal flood advisories or beach hazards.
- Grey Shading: Dense fog advisories, mostly for the North Bay valleys and the Delta.
- Clear Blue/White: That’s the high-pressure system keeping things sunny but smoggy.
There are no red-outlined boxes indicating a tornado warning. If there were, you’d see them concentrated around cold fronts or intense convective cells, neither of which are currently over the 7x7.
The Science: Can San Francisco Actually Get Tornadoes?
Yeah, they can. It’s just super rare. Meteorologists like Karleisa Rogacheski at the NWS have pointed out that while California doesn't get the massive EF5 monsters you see in Kansas, we do get "cold-core" funnels.

These usually happen when a very cold storm system moves over the relatively warm Pacific. The air starts to rise quickly, it gets a little spin from the terrain—the hills of SF are great for this—and suddenly you’ve got a weak tornado or a waterspout.
Recent History of Bay Area Twisters
- January 2026 (This Week): We saw some brief warnings in San Mateo and Santa Cruz on Monday. That likely fueled the search for a map today.
- December 2024: The "Big Scare" where a warning was issued for the city itself.
- March 2023: Several small tornadoes touched down in the Central Valley and one even damaged a mobile home park in Carpinteria further south.
Most "tornadoes" here are technically EF0 or EF1. They’ll knock over a fence, rip some shingles off a Victorian house in the Haight, or toss a patio chair. They aren't going to level a skyscraper.
How to Read a Real-Time Map Without Panicking
When you’re looking for a tornado warning San Francisco today map, you want to go straight to the source. Don't trust a screenshot on X (formerly Twitter) that might be from three years ago.
Go to weather.gov/mtr. That’s the Monterey office that covers San Francisco. If there’s a red polygon on that map, that’s a warning. If it’s a yellow polygon, it’s a Severe Thunderstorm Warning.

Pro tip: If the sun is out and the wind is light, you’re safe. Tornadoes need "juice"—moisture, instability, and wind shear. Today’s weather is basically the "anti-juice." We have a ridge of high pressure which acts like a lid, squashing any potential storms before they can start.
What You Should Actually Prepare For Today
Since a tornado isn't happening, what should you actually worry about?
Honestly, the Spare the Air alert is the bigger deal. It’s illegal to burn wood in your fireplace today. The air quality is "Moderate" to "Unhealthy for Sensitive Groups" because all that wood smoke and car exhaust is getting trapped near the ground.
Also, if you're planning on heading to Ocean Beach or Baker Beach, stay off the rocks. The NWS is reporting breaking waves between 7 to 12 feet. Sneaker waves are no joke—they look like small waves until they suddenly surge 50 feet further up the sand than you expected.
Actionable Steps for SF Weather Safety
- Check the AQI: Use AirNow.gov to see if you should be wearing a mask if you have asthma.
- Update your Alerts: Make sure "Emergency Alerts" are turned ON in your iPhone or Android settings.
- Verify the Source: If you see a "warning" map, check the timestamp. If it doesn't say "January 15, 2026," it’s junk.
- Stay Back from the Surf: If you’re at the coast, keep your eyes on the water. Never turn your back on the ocean during a Beach Hazards Statement.
Basically, keep your umbrella handy for some potential rain late next week, but leave the "Wizard of Oz" storm cellar preparations for another day. San Francisco is currently under a "boring weather" pattern, which, given our history of atmospheric rivers, is actually kind of a relief.
