(Updated at 3 p.m.) A widespread outbreak of severe weather is expected this evening, prompting a Tornado Watch for Arlington and much of the region.

Forecasters say the threats include “damaging and locally destructive hurricane-force winds, along with the potential for large hail and tornadoes, even strong tornadoes.”

Winds in excess of 70 miles per hour are possible.

The Tornado Watch is in effect until 9 p.m.

Arlington Public Schools, meanwhile, is closing facilities early today due to the weather threat. From a School Talk email to families:

Due to forecasted severe weather, Arlington Public Schools will shift to virtual operations today, Aug. 7, at 4 p.m. All APS facilities and programs held after 4 p.m. are canceled unless otherwise stated.

Extracurricular [activities], games, team practices, field trips, adult education classes and programs in schools and on school grounds are canceled this evening. For your safety, we strongly urge the community to stay off the roads between the hours of 4 and 8 p.m.

Federal government and Arlington National Cemetery are also closing early today, at 3 p.m., while Arlington County government offices are closing at 4 p.m.

The expected outbreak follows the storms just over a week ago that toppled trees throughout Arlington and knocked out power to more than 34,000 Dominion customers.

More from the National Weather Service:

…SEVERE WEATHER OUTBREAK EXPECTED OVER THE MID-ATLANTIC REGION BETWEEN 2 PM AND 10 PM TODAY, INCLUDING THE GREATER BALTIMORE/WASHINGTON METROPOLITAN AREAS…

An outbreak of severe storms is expected this afternoon and evening across the greater Baltimore/Washington region, with numerous severe thunderstorms expected. There is a significant threat for damaging and locally destructive hurricane-force winds, along with the potential for large hail and tornadoes, even strong tornadoes.

The timing of this outbreak varies with your location. West of the Blue Ridge Mountains, you can expect the storms to arrive between 12 Noon and 3 PM. East of the Blue Ridge Mountains, timing will be from 4 PM to 8 PM. The greater Baltimore/Washington Metropolitan Areas can expect the storms to arrive between 5 PM and 7 PM.

Now is the time to review your severe weather safety procedures for the possibility of dangerous weather today. Do not be outdoors when the storms arrive. When you hear thunder, go indoors to a sturdy building or structure. While seeking shelter indoors, go to the lowest floor to an interior room. Stay away from windows. Those in mobile homes or weaker structures should plan ahead of time to shelter in a stronger shelter. Be prepared for extended power outages, and the potential for some roads to be blocked by fallen trees.

For the after-event cleanup, do not go outside until 30 minutes after you hear the last thunder, otherwise you will be still susceptible to lightning strikes. Be aware of downed power lines and unstable branches and trees.

Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings. If a Severe Thunderstorm Warning or Tornado Warning is issued for your area, move to a place of safety, ideally in an interior room on the lowest level of a sturdy building.

Much of the D.C. area, including Arlington, is under a 4 out of 5 risk of severe weather, a rare designation not seen in the region in more than a decade.
