National Weather Service Warns Against Dangerous Rainfall, Tropical Storm

-

The National Weather Service (NWS) issued a tropical storm watch for the District and areas along the Interstate 95 corridor.

The DC area is likely to experience significant flooding due to Tropical Storm Isaias which has been moving towards the region late Monday.

“Due to Tropical Storm Isaias’ threat to our area, a Tropical Storm Watch has been issued for counties along the I-95 corridor and east. Flash Flooding will likely be our biggest impact Mon eve – Tue eve. Tidal/coastal flooding (Tue and Tue eve) is also a concern. Stay informed,” the agency said in a tweeted announcement.

Three to six inches of rain is expected and it could lead to “significant flash flooding of small streams and creeks Monday night into Tuesday evening,” according to NWS.

The Tropical Storm Watch is in effect for Anne Arundel, Arlington/Falls Church/Alexandria, Charles, District of Columbia, Fairfax, King George, Prince Georges, Prince William/Manassas/Manassas Park, Southeast Harford, Southern Baltimore, and Stafford.

DC area residents are advised to protect against life-threatening rainfall flooding, whose potential impacts may include many evacuations and rescues; rivers and tributaries rapidly overflowing their banks; and flood waters entering many structures causing some to become uninhabitable or washed away.

Dangerous wind may cause significant impacts across southern Maryland such as some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds; several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some roads may become impassable from large debris. Power and communications outages are also possible.

Limited impacts of hazardous wind, including scattered power outages, are possible across the Washington metro area.
