4 To 6 Inches Of Rain In Baltimore Area, More On Way: NWS

BALTIMORE, MD — A flood warning is in effect until 6:15 p.m. Tuesday for parts of Baltimore City and Baltimore County. The National Weather Service extended its original warning, which was set to expire hours earlier.

About 4 to 6 inches of rain have fallen since Monday night, with around an inch of rainfall reported in the last hour, the National Weather Service reported after 10:30 a.m.

Rain gauges and radar indicated moderate to heavy rain was continuing and would worsen flooding.

"Flooding is ongoing on Gunpowder Falls, with moderate flooding occurring near Glencoe," the National Weather Service warned. "These flood conditions will persist at least through the afternoon."

Authorities said these areas may experience flooding: Baltimore, Pikesville, Cockeysville, Towson, Catonsville, Woodlawn, Randallstown, Owings Mills, Milford Mill, Reisterstown, Lochearn, Arbutus, Mays Chapel, Timonium, Hampton, Lutherville-Timonium, Garrison, Lutherville, Freeland and Upperco.

The flood warning means that flooding is occurring or is imminent. Drivers who come across roads covered in water should turn around; don't drown.

Law enforcement officials were reporting flooding across western Baltimore County and northwestern Baltimore City before 8:30 a.m., according to the National Weather Service.

Mt. Carmel Road is closed across Peggy's Run, where a bridge has collapsed, officials said.

The Maryland Transit Administration advised that Penn line trains may experience delays since heavy rain and poor visibility could reduce track speeds.

The Baltimore metro area is also under a flash flood watch until 6 p.m. on Wednesday, July 25.

A flash flood watch means that there is the potential for flash flooding, which can be life-threatening. Heavy rain in a short time can lead to flash flooding, or a rapid rise in water level.

Because the ground is already saturated from the weekend downpours, officials say heavy rain could lead to flash flooding.

Roads and poorly drained areas can quickly become inundated during a flash flood. Streams and creeks could leave their banks, flooding nearby properties. Residents should monitor the forecast and be prepared to take action if a flash flood warning is issued, according to the National Weather Service.
