Understanding Severe Thunderstorm Warnings in the Bay Area

The National Weather Service (NWS) issues various alerts to warn residents about impending severe weather. Understanding the difference between these alerts is vital for your safety. Knowing what a severe thunderstorm warning, tornado warning, or flash flood warning signifies allows you to react appropriately and promptly.

• Severe Thunderstorm Warning: This means severe thunderstorms are happening in your area. Expect damaging winds, large hail, and heavy rain. Take immediate shelter.
• Tornado Warning: This indicates a tornado has been sighted or indicated by weather radar. Take immediate shelter in a sturdy building, away from windows.
• Flash Flood Warning: This means a flash flood is occurring. Never drive or walk through floodwaters; turn around, don't drown.

How to Receive NWS Alerts:

• NOAA Weather Radio: A dedicated weather radio provides continuous updates and warnings.
• Smartphone Apps: Download weather apps like the NWS app or a reputable weather service provider. Enable location services and emergency alerts.
• Local News: Stay tuned to local news channels and websites for up-to-date weather information and Bay Area weather alerts.

Remember, a watch means conditions are favorable for severe weather to develop, while a warning means severe weather is happening or imminent. Warnings demand immediate action.

Safety Precautions During a Bay Area Thunderstorm

Your actions during a severe thunderstorm drastically impact your safety. Knowing what to do both indoors and outdoors is essential.

Indoor Safety:

• Seek shelter in a sturdy building.
• Stay away from windows and exterior doors.
• Unplug electronic devices to protect them from power surges.
• Avoid using landline phones during a thunderstorm. Cell phones are generally safer.

Outdoor Safety:

• Seek immediate shelter indoors or in a hard-topped vehicle.
• Avoid high ground, open fields, and bodies of water. These areas are more susceptible to lightning strikes.
• Avoid being near metal objects like fences or power lines.
• Be aware of the signs of an approaching thunderstorm: darkened skies, strong winds, distant rumbling.

Lightning Safety:

Follow the 30/30 rule: If you can hear thunder within 30 seconds of seeing lightning, seek shelter immediately and wait 30 minutes after the last thunder before resuming outdoor activities. Lightning can strike miles away from the center of a thunderstorm.

Flood Safety:

Never drive or walk through floodwaters. The depth of water may be deceiving, and currents can be strong enough to sweep you away. Turn around, don't drown.

Protecting Your Property During a Bay Area Thunderstorm

Protecting your property requires preparation before, during, and after a storm.

• Before the storm: Secure loose objects like patio furniture, garbage cans, and outdoor decorations that could become airborne projectiles. Trim trees and shrubs near your house to prevent damage from strong winds.
• During the storm: Close and secure all windows and doors. Consider boarding up windows if you anticipate extreme winds.
• Power outages: Have flashlights, battery-powered radios, and extra batteries readily available. Consider having a generator for essential appliances.
• Flood prevention: Ensure gutters and downspouts are clean and clear to prevent water from accumulating around your foundation.

Post-Thunderstorm Actions in the Bay Area

After the storm passes, assessing the situation and taking appropriate action is crucial.

• Check for damage: Inspect your home and property for damage. Look for downed power lines, broken trees, and signs of flooding.
• Report hazards: Report downed power lines and other hazards to the appropriate authorities immediately.
• Power outage: Report power outages to your utility company.
• Neighborly checks: Check on your neighbors, particularly those who may be elderly or vulnerable.
• Debris removal: Clean up debris safely, wearing appropriate safety gear and being aware of potential hazards like broken glass or sharp objects.
• Stay informed: Continue to monitor weather forecasts and reports for updates on ongoing conditions.
