DC area flood warnings extended on Mother’s Day

D.C. area jurisdictions are warning people not to drive through floodwaters this Mother’s Day, as flood warnings and watches continue to be issued.

Storm Team4’s meteorologists said that the weather is expected to give way for a dry afternoon, even as flood waters persist.

“Flooding concerns persist, but rain is lighter now as this latest system passes by,” Storm Team4 Meteorologist Briana Bermensolo told WTOP. “The National Weather Service let many advisories and warnings expire in Northern Virginia and the District but still be on high alert for standing water on roads and downed trees due to breezy conditions [and] soaked grounds.”

Flood Warnings

The following localities are under a flood warning until 6 p.m. Sunday, particularly for the areas adjacent to the Potomac River.

  • D.C.
  • Frederick County, Maryland
  • Montgomery County, Maryland
  • Washington County, Maryland
  • Fairfax County, Virginia
  • Loudoun County, Virginia

There’s also a risk of flooding in some coastal areas, particularly around the time of high tide. The next high tides in D.C. are at 1:58 a.m. and 2:56 a.m.

Coastal Flood Warnings that kick in Sunday night include:   

  • D.C.
  • St. Mary’s County, Maryland

While D.C. and St. Mary’s County are under flood watches during the day on Sunday, flooding is expected to get worse by nightfall. That warning should expire by Monday night.

Under the Coastal Flood Advisory, up to a foot of water could flood in low lying areas on Sunday afternoon.

During the Coastal Flood Warning overnight Sunday, water could rise one to two feet above ground level in low lying areas because of tidal flooding.

It will also be unseasonably cold Sunday with highs in the mid 50s — around 20 degrees lower than the daily average.

And don’t worry if the (extremely belated) April showers are getting in the way of your May flowers. The week looks likely to start on a cloudy note before temperatures approach the 70 degree mark.


SUNDAY: AM clouds and drizzle. Drier PM. Very chilly. Wind 10 to 20 mph. Highs mid 50s.

SUNDAY NIGHT: Partly cloudy. Cold. Wind 5 to 10 mph. Temperatures in  the upper 30s (burbs) to lower 40s (downtown).

MONDAY: Partly Sunny. Milder. Highs mid 60s

TUESDAY: Mostly Sunny. Warm. Highs near 70.

WEDNESDAY: Mostly sunny. Highs mid 70s.
