Flood Warning Issued As Runoff From Heavy Rain Takes Toll

BALTIMORE, MD — The sun may be out Thursday morning but flood dangers remain. The National Weather Service issued a flood warning for parts of central Maryland until Thursday night.

Weather officials say that runoff from the recent heavy rainfall will cause flooding of small creeks and streams, urban areas, highways, streets, underpasses, drainage areas and other low-lying spots.

Flooding was occurring in waterways across the region, based on gauge readings at 11:30 a.m. on Thursday, according to the National Weather Service.

The Patapsco River has flooded between Catonsville and Pumphrey. The Gunpowder Falls was also still experiencing "significant flooding," the weather service warned, despite water levels receding.

During a flood warning, flooding is imminent or occurring. Drivers should turn around if they come across flooded roads, and pedestrians should not attempt to walk through flood waters.

In particular, weather officials said the areas that may experience flooding are Baltimore, Columbia, Middle River, Cockeysville, Elkridge, Ellicott City, Dundalk, Catonsville, Essex, Woodlawn, Carney, Perry Hall, Arbutus, Rosedale, Rossville, Brooklyn Park, Mays Chapel, Timonium, White Marsh and Bowleys Quarters.

The flood warning is in effect until 7 p.m. on Thursday, July 26, for these areas:

• Baltimore City
