Understanding Thunderstorm Watches and Warnings

It's vital to understand the difference between a thunderstorm watch and a thunderstorm warning. These alerts, issued by the National Weather Service (NWS), indicate different levels of immediate danger:

• Thunderstorm Watch: Conditions are favorable for severe thunderstorms to develop in and around the Bay Area. This is a time to prepare. Monitor the weather closely and stay informed. Have your emergency plan in place.

• Thunderstorm Warning: Severe thunderstorms are happening now, or are imminent, in your area. Take immediate action to protect yourself and your property. This is not the time to wait and see. Seek shelter immediately.

The NWS uses sophisticated radar and weather models to issue these alerts. They assess various factors, including atmospheric instability, wind shear, and moisture levels, to determine the likelihood and severity of thunderstorms. Depending on the specific threats, the warning may include additional information, like a high wind warning or a flash flood warning.

Currently, scattered thunderstorms are impacting portions of the Bay Area. Moderate to heavy rain is falling in parts of San Francisco, Oakland, and San Jose. Reports of high winds are coming in from the East Bay hills, with gusts exceeding 40 mph in some areas. Hail the size of quarters has been reported in the South Bay. The National Weather Service is closely monitoring the situation and providing updates. (A map showing affected areas would be inserted here in a live version.) Power outages are currently being reported in several neighborhoods across the region.

Expected Impacts

The severe thunderstorms impacting the Bay Area are expected to bring:

• Heavy Rainfall and Potential Flooding: Low-lying areas and areas with poor drainage are particularly vulnerable to flash flooding.
• High Winds and Potential for Downed Trees and Power Lines: Strong winds can cause significant damage, leading to power outages and hazardous conditions. Be cautious near trees and power lines.
• Large Hail: Hail can cause damage to property, vehicles, and crops.
• Flash Flooding: Rapid rises in water levels can occur in creeks, streams, and low-lying areas with little warning.

Areas along the coast and in the East Bay hills are considered particularly high-risk due to their geographic features and potential for localized flooding and wind damage.

Safety Precautions During Severe Thunderstorms

Your safety is paramount during severe thunderstorms. Follow these crucial precautions:

• Stay indoors during a thunderstorm warning. Seek shelter in a sturdy building.
• Avoid contact with water and metal objects. These are excellent conductors of electricity.
• Unplug electronic devices to protect them from power surges.
• Charge cell phones and other electronic devices in case of a power outage.
• Have a plan for emergency communication. Designate an out-of-area contact person.
• Know the location of your nearest shelter in case evacuation is necessary.
• Monitor weather updates from reliable sources like the NWS.
