Severe Thunderstorm Warning Issued For The Bay Area: What You Need To Know

Understanding the Severe Thunderstorm Warning

A Severe Thunderstorm Warning means that severe thunderstorms are happening now in your area. This is not a drill; dangerous weather conditions with the potential for significant damage are imminent. It's crucial to distinguish between a watch and a warning:

Watch: A watch means that conditions are favorable for severe thunderstorms to develop. Stay informed and be prepared to take action.
Warning: A Severe Thunderstorm Warning means severe thunderstorms are occurring and pose an immediate threat. Take action immediately.
When a warning is issued, dangerous weather is imminent.
Take action immediately upon hearing a warning.

A severe thunderstorm is defined by the National Weather Service (NWS) as a thunderstorm that produces one or more of the following:

Winds of 58 mph or greater
Hail one inch in diameter or larger
Heavy rainfall leading to flash flooding

Safety Measures During a Severe Thunderstorm

Your safety is paramount during a Severe Thunderstorm Warning. Knowing how to protect yourself, both indoors and outdoors, is key.

Protecting Yourself Indoors

If you're indoors when a Severe Thunderstorm Warning is issued, follow these crucial steps:

Stay away from windows and doors. These are the most vulnerable areas to damage from high winds and hail.
Unplug electronic devices to prevent damage from lightning strikes. Surge protectors can offer additional protection, but are not a guarantee.
Find a safe, interior room away from windows. An interior closet or hallway is ideal.

Remain indoors until the warning is lifted by official sources.

Staying Safe Outdoors

Being caught outdoors during a severe thunderstorm is extremely dangerous. If you are caught outside:

Seek immediate shelter in a sturdy building. A home or office building is your safest option.
If caught in the open, avoid tall objects like trees, which are more likely to be struck by lightning.
Never shelter under a lone tree. This is extremely dangerous due to the risk of lightning strikes.
Get inside a vehicle if possible. A vehicle offers relatively good protection from lightning, but avoid touching any metal parts.

Lightning strikes are a significant danger during thunderstorms. To minimize risk:

Avoid open fields and bodies of water.
If you feel your hair stand on end, or you hear a crackling sound, seek immediate shelter. Lightning is likely to strike very soon.

Preparing for Severe Thunderstorms in the Bay Area

The Bay Area's thunderstorm season typically runs from late spring to early fall. Proactive preparation can significantly reduce risks and minimize the impact of severe weather.

Develop an emergency plan including communication strategies with family and friends. Determine a meeting place in case of separation.
Charge electronic devices regularly to ensure you have access to information and communication during a power outage.
Have a supply of emergency essentials readily available, including water (at least one gallon per person per day), non-perishable food, a flashlight with extra batteries, a first-aid kit, and any necessary medications.
Monitor weather forecasts regularly through reliable sources like the NWS and local news channels. Utilize weather apps for real-time alerts and updates.
