Flood Warning Issued For 4 Counties Plus Baltimore City

BALTIMORE, MD — A flood warning has been issued for four counties Monday night as well as Baltimore City. The National Weather Service issued the warning based on radar after 9:20 p.m. indicating showers and isolated thunderstorms would cause flooding.

Up to an inch of rain had fallen by 8:50 p.m., and another inch was anticipated before the end of the warning period, weather officials said. Locally higher amounts were possible.

Streams and creeks will rise from runoff due to heavy rain, authorities warned.

The flood warning is in effect until 3:15 a.m. Tuesday.

The following areas are impacted:

• Anne Arundel County - northwestern
• Baltimore City - northwestern
• Baltimore County - southwestern
• Carroll County - southeastern
• Howard County - eastern

The following areas may experience flooding, according to the flood warning: Baltimore, Pikesville, Elkridge, Catonsville, Woodlawn, Randallstown, Owings Mills, Milford Mill, Reisterstown, Lochearn, Arbutus, Hampstead, Manchester, Linthicum, Garrison, Lansdowne, Upperco, Brooklandville, Halethorpe and Mcdonogh.

Drivers who come across flooded roads or those with water of unknown depth should turn around; don't drown.

Flash Flood Watch Still In Effect

The Baltimore metro area is also under a flash flood watch until 2 a.m. 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.

These counties are under the flash flood watch, in addition to Baltimore City:

• Anne Arundel
• Baltimore
• Calvert
• Carroll
• Charles
• Frederick
• Harford
• Howard
• Montgomery
• Prince George's
• St. Mary's
• Washington
