As thunderstorms advance into the evening, the National Weather Service has issued a Severe Thunderstorm Watch for Alexandria and the rest of the D.C. region.
Capital Weather forecasters say multiple rounds of storms are possible Tuesday afternoon and evening. The Severe Thunderstorm Watch is in effect until 10 p.m.
“Scattered severe thunderstorms are expected this afternoon and evening,” the NWS says. “Damaging wind gusts are the primary threat, although large hail and a tornado are possible. A few instances of flash flooding are also possible.”
A watch means severe storms are possible. Residents are advised to seek shelter if NWS issues a Severe Thunderstorm Warning.
