More than 800,000 Virginians have signed up to participate in a statewide tornado drill.
The drill, set for 9:45 a.m. Tuesday, is a joint effort between the state Department of Emergency Management and the National Weather Service.
NOAA Weather Radio will broadcast a test warning from the National Weather Service, which will then be aired by television and radio stations.
When the test warning is heard, participants should move to a safe area, such as a basement, bathroom or closet on the lowest level of a building.
Over the last two years, 62 tornadoes have hit Virginia. Ten people were killed, more than 100 were injured and dozens of homes and businesses were destroyed.
