San Francisco, CA – A weak system could cause isolated thunderstorms across the Bay Area beginning Monday night, with the threat lasting until Wednesday evening.
The National Weather Service Bay Area office predicts up to a 20% chance of thunderstorms from San Francisco to Monterey.
The main concern is lightning strikes, but there is also the risk of small hail and gusty, erratic winds. Thunderstorms can form during the day or night, especially in inland valleys and higher elevations.
While the overall risk is considered minor, dry lightning has the potential to start wildfires in more fire-prone areas.
Residents should be weather-aware and prepared for unexpected changes, especially if traveling or recreating outside. When lightning strikes in the absence of significant rainfall, the risk of fire increases.
NWS officials remind residents that “when thunder roars, go indoors,” and that if they see a flash, they should go inside immediately. If storms intensify, there may be power outages and brief travel disruptions.
This weather pattern is not unusual for mid-April in California, but forecasters warn that the combination of dry fuels and potential lightning may increase local fire concerns. Updated alerts and safety tips will be shared on weather.gov/BayArea.
