San Francisco, CA – A weak system could spark isolated thunderstorms across the Bay Area starting Monday night, with the threat continuing through Wednesday evening.
According to the National Weather Service Bay Area office, there is up to a 20% chance of thunderstorms affecting areas from San Francisco to Monterey. Lightning strikes are the primary concern, with additional risks including small hail and gusty, erratic winds. Thunderstorms may develop during both day and nighttime hours, particularly in inland valleys and the higher terrain.
While the overall risk is considered minor, dry lightning could ignite wildfires in more fire-prone areas. Residents are advised to stay weather-aware and be prepared for sudden changes, especially if traveling or recreating outdoors. Fire danger increases when lightning occurs without significant rainfall.
NWS officials remind residents: “When thunder roars, go indoors,” and to head inside immediately if they see a flash. Power outages and brief travel disruptions are also possible if storms intensify.
This weather pattern is not unusual for mid-April in California, but forecasters note the combination of dry fuels and potential lightning could heighten local fire concerns. Updated alerts and safety tips will be shared on weather.gov/BayArea.
