Tornado Risk As Hazardous Weather Outlook Issued For NoVA, DC

WASHINGTON, DC — There is a risk of tornadoes and storm damage on Monday as thunderstorms push through Washington, D.C., and northern Virginia, the National Weather Service said. The agency issued a hazardous weather outlook for the I-95 corridor through northern Virginia and the District of Columbia.

"Scattered instances of wind damage or a tornado or waterspout" could occur due to the showers and thunderstorms late Monday morning through mid-afternoon, according to the weather service.

Drivers should give themselves extra time to get to their destinations because some roads may be affected by water.

An active weather pattern with moderate/heavy rain moving through this morning, the NWS posted on Facebook. Scattered showers/thunderstorms possible through the afternoon, a few may be severe. Precipitation winds down early this evening along I-95. Snow is likely along and west of the Allegheny Front.

Showers or thunderstorms may produce scattered instances of wind damage or a tornado or waterspout from late this morning through mid-afternoon. An isolated instance of flooding or two is possible, as well.

The National Weather Service also issued a gale warning Monday for the Maryland portion of the Chesapeake Bay, tidal Potomac River and adjoining tidal estuaries until 6 p.m. Mariners should stay in port, seek safe harbor or alter course, as strong winds and waves could capsize vessels.

A coastal flood advisory is in effect for DC from 5 to 10 p.m. Officials advise up to 1.5 feet of inundation is possible above ground in low-lying areas because of tidal flooding.

Up to one half foot of inundation above ground level is expected in low lying areas due to tidal flooding along the shoreline in the District of Columbia. The risk peaks from 5 p.m. this afternoon to 10 p.m., especially around high tide, which is 8:03 p.m.

Shoreline inundation is expected along portions of the seawall adjacent to Ohio Drive and the Hains Point Loop Road, and near the Tidal Basin and Jefferson Memorial. Minor shoreline inundation up to one foot above ground is possible elsewhere.

Here's the latest forecast:

Monday: Rain before 11am, then showers and possibly a thunderstorm between 11am and 4pm, then a chance of showers after 4pm. Some of the storms could produce gusty winds. High near 68.
