The National Weather Service has issued a Tornado Watch for the City of Alexandria and the surrounding area until 10:00 PM THIS evening (Monday, April 20, 2015). What’s the difference between a tornado watch and a tornado warning? Check out this link.
A tornado watch is issued when weather conditions are favorable for the development of severe thunderstorms that are capable of producing tornadoes.
SUMMARY…THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER NORTHERN VA AND
WESTERN MD THIS AFTERNOON…TRACKING ACROSS THE WATCH AREA.
DAMAGING WINDS AND HAIL ARE THE MAIN THREATS. HOWEVER…BACKED LOW
LEVEL WINDS NEAR A WARM FRONT MAY BE SUFFICIENT TO ENHANCE THE RISK
OF ISOLATED TORNADOES OVER NORTHERN PARTS OF THE WATCH.
THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 90 STATUTE
MILES EAST AND WEST OF A LINE FROM 30 MILES EAST SOUTHEAST OF
CHARLOTTESVILLE VIRGINIA TO 25 MILES NORTH OF HARRISBURG
PENNSYLVANIA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU0).
REMEMBER…A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.
