Tornado Watch Cancelled

Update: The Tornado Watch has been canceled.

The National Weather Service has issued a Tornado Watch across a large area that includes Ashburn. The watch remains in effect until 4 p.m. if not called off sooner.

A Tornado Watch means that conditions are favorable for the development of severe thunderstorms and multiple tornadoes in and close to the watch area, according to the Weather Channel's Web site. People in the affected areas are encouraged to be vigilant in preparation for severe weather.

The alert would not be elevated to a Tornado Warning unless a tornado is seen by spotters or detected on radar, and is occurring or imminent in the warning area. If a tornado warning is issued, people in the affected area are strongly encouraged to take cover immediately. Information about preparing for a tornado can be found here.
