Severe Storms Expected Near End of Trick-or-Treating in Alexandria

A Tornado Watch has been issued for Alexandria and the D.C. region, with severe storms expected near the tail end of tonight’s trick-or-treating.

Alexandria has no official trick-or-treating time, but traditionally little ghouls and goblins prowl the streets in search of free candy between about 6-8 p.m. Forecasters warn that a line of storms packing rain and gusty winds will reach Alexandria around 9 p.m.

People should should seek shelter well ahead of the storms, forecasters say. The storms are expected to arrive quickly, bringing heavy rain and dangerous winds that may topple trees and send loose debris flying. Additional isolated storms are possible ahead of the main squall line.

The National Weather Service issued a special statement about the threat:

…DAMAGING LINE OF THUNDERSTORMS LIKELY TO MOVE EAST ACROSS THE AREA BETWEEN MID AFTERNOON AND MIDNIGHT…

A LINE OF THUNDERSTORMS IS EXPECTED TO MOVE EAST ACROSS THE REGION. THESE STORMS WILL BRING THE POSSIBILITY OF DAMAGING WIND  GUSTS AND ISOLATED TORNADOES. PLEASE BE SHELTERED WHEN THESE  THUNDERSTORMS PASS THROUGH YOUR AREA.

THE MOST LIKELY TIMING OF THE LINE RANGES FROM MID TO LATE AFTERNOON FOR THE POTOMAC HIGHLANDS, TO THE EVENING FOR THE BALTIMORE/WASHINGTON METROS, TO BETWEEN 9PM AND MIDNIGHT FOR AREAS EAST OF I-95 TO THE CHESAPEAKE BAY. THE STORMS WILL LIKELY LAST AN HOUR OR LESS IN MOST AREAS.

STAY INFORMED. FOR MORE EXACT TIMING FOR YOUR LOCATION, CONSULT THE FORECAST FOR YOUR COMMUNITY AT OUR WEBSITE WEATHER.GOV OR OUR FACEBOOK OR TWITTER FEEDS FOR NATIONAL WEATHER SERVICE BALTIMORE/WASHINGTON.
