A Severe Thunderstorm Watch is issued by the National Weather Service when conditions are favorable for the development of severe thunderstorms in and close to the watch area.

Precautions when a Severe Thunderstorm Watch is issued:
Unplug electronic equipment. Power surges from lightning can damage computers, monitors and TVs, and cause sparks that might start a fire.
If it’s safe, bring in outdoor furniture and other items that could blow away. These may become a hazard.
Stay inside a building or car that’s not a convertible.
Rubber tires won’t protect you from lightning so avoid touching metal inside the car.
Close windows, shutters, blinds, shades, and curtains. This will help keep out wind, rain, and broken glass.
Make sure outside doors are securely closed. This will help keep out wind and rain.
