DC roads under coastal flood advisory until Tuesday after heavy weekend rain

UPPER MARLBORO, Md. - Water is finally starting to subside in Prince George's County as heavy rain flooded roadways throughout the DC-metro area.

The bridge at Water Street in Upper Marlboro still has puddles of water after being covered Sunday night.

Montgomery, Prince George's, Frederick and Washington Counties are under a flood warning through Tuesday, as well as Loudoun and Fairfax Counties in Virginia.

DC is under a coastal flood advisory through Tuesday as saturated rivers and creeks begin to recede.

Low-lying areas are particularly prone to flooding, even after the rain has stopped. Georgetown, Alexandria, as well as Roosevelt Island are being closely watched by the National Weather Service.

The rain in DC officially hit record levels for the year, making 2018 the wettest year in recorded history for the District, based on precipitation at Reagan National.

Over the weekend, cars were swept off the roads, and even a llama had to be rescued by area crews from the water.

In Maryland, Whites Ferry in Montgomery County remains closed Monday for water and debris.

In Laurel, Riverfront Park and Kidwell Services parking lot at 1 Main Street remains closed due to flooding. City officials ask people not use the park since it will remain closed until further notice.

In Virginia, Piper Lane was closed Monday due to flooding. Commuters taking the VRE Manassas Line originating at Broad Run/Airport can access the Broad Run commuter lot via main airport entrance on Prince William Parkway.

The excess water has also led to sewer overflows in Maryland in Charles and Prince George's Counties. Charles County's Mattawoman facility experienced an overflow of 33,000 gallons of untreated wastewater.

In Prince George's County, there were sewer overflows at WSSC's Broad Creek Wastewater Pumping Station in Fort Washington, and the other near WSSC's Piscataway Water Resource Recovery Facility (WRRF) in Accokeek.

Those driving through the area Monday are asked to keep a look out for standing water in roads and to turn around instead of driving through it.
