Flood Warning Extended for Howard, Anne Arundel Counties

A flood warning has been extended into Thursday afternoon for parts of Anne Arundel and Howard counties as river levels rise.

UPDATED at 10:55 a.m. COLUMBIA, MD — With an inch of rain already on the ground early Thursday, predictions of 1 to 3 inches more likely, and river levels rising, the National Weather Service has extended a flood warning for parts of Howard and Anne Arundel counties.

The flood warning is in effect until 2 p.m. on Thursday, Sept. 29. Drivers should be aware of standing water, and if they encounter flooded roadways, motorists are encouraged to turn around; don't drown.

The National Weather Service says gauges at 10:44 a.m. showed water rising on area rivers, especially the Little Patuxent and Patapsco Rivers. These streams could approach their flood levels early Thursday afternoon, especially if more heavy rain saturates the area. An updated forecast says that there will be a bit of a breather, but heavy rains of 1 to 3 inches are likely between noon and 8 p.m. Thursday.
