San Francisco, CA – The Bay Area is gearing up for a stretch of wet weather as the National Weather Service (NWS) forecasts steady rainfall and potential thunderstorms beginning Monday morning. Forecasters are warning residents to prepare for 1 to 3 inches of rain, depending on elevation, and to expect lightning, gusty winds, and localized flooding in certain areas.
NWS Issues Warnings for Bay Area Rain and Storms
According to the NWS San Francisco Bay Area office, most lower-elevation regions can expect between 1 and 2 inches of rainfall, while higher elevations could see up to 3 inches or more. Meteorologists noted that heavier downpours are likely in areas hit by thunderstorms, raising concerns about minor flooding in urban and small stream zones.
“We’re looking at a storm system that could bring a mix of steady rain and pockets of thunderstorm activity,” the NWS said in a statement. “Drivers should be alert for water on the roads and potential delays during the morning commute.”
Thunderstorm Threat and Lightning Risks
The system moving in from the Pacific will bring unstable air, creating conditions ripe for isolated thunderstorms. Residents are urged to avoid open areas during lightning events and to stay indoors when thunder is heard nearby.
Lightning strikes and sudden wind gusts could also impact coastal and mountain areas, where trees and power lines remain vulnerable after recent weather events.
Cooler Temperatures to Accompany the Storm
The incoming storm will also bring cooler-than-usual temperatures, with highs in the mid-to-low 60s across the region. Combined with steady rain and wind, conditions will feel chilly throughout much of Monday and Tuesday.
Meteorologists say the scattered showers are expected to linger into Tuesday, with the possibility of additional thunderstorms before the system gradually weakens midweek.
Travel and Safety Precautions for Residents
Officials are reminding Bay Area residents to check travel routes ahead of time and avoid driving through flooded roadways, as even shallow water can disable vehicles or create hazardous conditions.
Commuters are encouraged to use public transit where possible and to allow extra travel time Monday morning. Homeowners should also clear gutters and storm drains to prevent backup flooding during heavier downpours.
What to Expect After Tuesday
While the heaviest rainfall is expected early in the week, light scattered showers may continue through Wednesday in parts of the North Bay and East Bay hills. Drier conditions should return by Thursday, with gradual warming expected by the weekend.
Weather officials say this early-week system is a reminder that the Bay Area’s rainy season is beginning, urging residents to stay prepared as more Pacific storms approach in the coming weeks.
