Monday has the potential for even more active weather.
Arlington, D.C. and other parts of the region are under an “enhanced” risk of severe weather, according to a National Weather Service outlook. Severe winds are likely, according to NWS forecasters, noting the “seriousness” of the threat.
Meanwhile, large hail and even a tornado are also possible in the D.C. area.
According to NWS, this is the first time that D.C. has ever had a 45% or greater risk of severe winds on its next-day outlook.
The last instance of such a high probability of severe winds was the same-day outlook on Halloween day 2019.
Monday continues to look like a very busy & significant day across the region. We were upgraded to a level 3 out of 5 risk for severe storms overnight.
All hazards are on the table with even the potential for a couple tornadoes. Stay weather aware! #vawx #mdwx #dcwx #wvwx pic.twitter.com/mmTFL6ibHa
