Heavy Rain Triggers Flood Watch In Morris County: NWS

MORRIS COUNTY, NJ — A flood watch and hazardous weather outlook have been issued for Morris County, as heavy rains are predicted to slam the county Tuesday night into Wednesday.

One to three inches of rainfall are expected in the Morris County area, which may result in flooding of urban and poor drainage areas, according to the National Weather Service.

The watch is in effect through 8 p.m. on Tuesday, according to forecasters.

Widespread showers with possible thunderstorms are expected Tuesday. The rain showers could be heavy at times and could slowly move over the same areas, resulting in flash flooding, the NWS said.

"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas," NWS said.
