DC area in for strong thunderstorms, heavy rain overnight

Severe weather in the D.C. region brings a tornado watch for much of the D.C. region.



What to expect

The National Weather Service has issued a tornado watch until 3 a.m. for much of the D.C. region, including Maryland and Virginia suburbs. A tornado watch means damaging winds may cause trees and branches to topple. Power outages are possible.

“If you spot a tornado, go at once into the basement or small central room in a sturdy structure,” the National Weather Service said.

There is a severe weather threat that started late Sunday afternoon through early Monday morning, with the window for the biggest risk until 4 a.m. Monday.

The biggest threats are damaging winds and isolated tornadoes, the National Weather Service said.

“The severe storms will bring heavy blinding rain, strong damaging winds and there is a possibility for hail and even weak isolated tornadoes,” Storm Team4 meteorologist Clay Anderson said.

Between 5 to 8 p.m, areas northwest of Interstate 95 experienced the first round of storms.

The second round of storms, which will rake through the area overnight, will sweep through from west to east. The overnight storms are expected between midnight to 3 a.m. Monday.

Up to a half of an inch of rain is expected, posing a flood risk for areas vulnerable to heavy downpours.

“The main threat will be damaging winds … but an isolated tornado and isolated instances of flooding cannot be ruled out as well,” the National Weather Service said.

Meteorologists urge everyone to keep up with the forecasts and have multiple ways to get warnings. When the storms strike, seek shelter.

“Remember: When thunder roars, get inside and away from windows,” Storm Team4 meteorologist Steve Prinzivalli said.

Maryland Gov. Larry Hogan issued a statement Sunday, urging Marylanders to pay close attention to updated weather forecasts. “Residents should take every possible precaution, and stay indoors away from windows during thunderstorms,” he said. He also asked to pay attention to emergency alerts.
