A Statewide Tornado Drill Will Be Held In Virginia This Morning. The Drill Is An Annual Opportunity To Prepare Residents For Tornado Emergencies And To Test Public Warning Systems. At Approximately 9:45 A.M., The National Weather Service Will Send A Test Tornado Warning Test Over NOAA Weather Radios. The Test Signal Will Sound A Tone Alert, Show A Test Message Or Flash To Indicate A Message, Simulating What People Would Hear Or See During An Actual Tornado Warning. The Emergency Alert System Also Will Broadcast The Test Through All Radio And TV Stations.
