San Francisco is gearing up for a rough week as a powerful storm system barrels toward the Bay Area. Forecasters are warning of dangerous high winds, torrential rain, and enormous ocean waves that could cause widespread disruptions.
From midweek through the weekend, residents should prepare for potential power outages, hazardous travel conditions, and life-threatening coastal waters. Authorities are urging everyone to take precautions before the worst of the storm arrives.
Storm #1: High Winds Could Knock Out Power and Down Trees
The National Weather Service has issued a High Wind Watch starting Wednesday evening and lasting through Friday morning. Winds are expected to reach 35 to 40 mph, with gusts as high as 70 mph in some areas.
For those in the Marin Coastal Range and other elevated locations, gusts could exceed 80 mph, making it one of the strongest wind events of the season. These winds could easily knock down trees, power lines, and unsecured objects, leading to power outages and major disruptions.
If you live in an area prone to power outages, now is the time to charge your devices, gather flashlights, and secure anything that could be blown away outside your home.
Storm #2: Flash Flooding Could Turn Streets Into Rivers
Heavy rain will accompany the storm, and a Flood Watch has been issued from Wednesday evening through Saturday night. With the ground already saturated from recent rainfall, forecasters warn that additional rain could cause rivers and streams to overflow, leading to flash flooding in urban areas.
San Francisco, along with San Mateo, Santa Cruz, and Monterey counties, will be particularly vulnerable to rising water levels. Low-lying neighborhoods and poorly drained streets could quickly become impassable.
Residents in flood-prone areas should have an evacuation plan in place. Never attempt to drive through flooded roads—just six inches of moving water can sweep a car away.
Storm #3: Monster Waves to Create Life-Threatening Beach Conditions
As if the wind and rain weren’t enough, the storm will also bring extreme ocean conditions. A High Surf Warning will be in effect from Thursday afternoon through early Saturday morning.
West-facing beaches could see waves between 20 to 30 feet, with some reaching a staggering 45 feet. Even non-west-facing beaches will experience dangerous conditions, with waves up to 30 feet high.
Officials warn that these waves are powerful enough to sweep people off jetties, rocks, and even coastal trails. The combination of dangerous surf, strong rip currents, and unpredictable swells makes going anywhere near the water a serious risk. Beachgoers are urged to stay far away from the shoreline.
How to Prepare and Stay Safe
With a triple threat of wind, flooding, and rough surf, now is the time to get ready. Here’s what you can do to stay safe:
- Secure loose objects. Strong winds can turn outdoor furniture, decorations, and trash bins into dangerous projectiles. Bring them inside or anchor them down.
- Prepare for power outages. Keep flashlights, extra batteries, and portable chargers handy in case of blackouts.
- Avoid flooded areas. Never drive through standing water—it’s impossible to tell how deep it is.
- Stay away from the coast. Huge waves can be deadly, even if they seem far away. Watch the ocean from a safe distance.
- Stay informed. Sign up for emergency alerts and keep an eye on weather updates throughout the week.
Final Thoughts
San Francisco is no stranger to storms, but this one is bringing a dangerous mix of extreme weather. The combination of hurricane-force winds, potential flash flooding, and massive waves means everyone needs to stay alert.
If you haven’t already made preparations, now is the time. Stay indoors during the worst of the storm, avoid risky travel, and most importantly—stay safe. This is shaping up to be one of the most intense weather events of the season, and it’s not one to take lightly.
