Several flood advisories and warnings were in effect across New York City and the Lower Hudson Valley early Monday as heavy rain and thunderstorms moved through the region.
Flood advisory, flash flood warning issued
The National Weather Service issued a flood advisory for New York City and Westchester County from 5:30 a.m. to 8:15 a.m. Monday. A broader flood watch remains in effect through Monday evening.
Forecasters said thunderstorms moving north from the south could produce 0.5 to 1 inch of rain in a short period, leading to minor flooding. Areas expected to see the greatest impacts include Queens, Brooklyn, Yonkers, New Rochelle, Rye and parts of northern New Jersey.
Additional thunderstorms later Monday could bring rainfall rates of 1 to 2 inches per hour, particularly across New
York City and nearby parts of Westchester County.
Flash flood warning for three counties
A flash flood warning was also issued until 7:45 a.m. for Rockland, Westchester and Putnam counties.
The National Weather Service said 1 to 1.5 inches of rain had already fallen, with another 1 to 2 inches possible by 8 a.m. Communities under the warning include New City, Ossining, Peekskill, Monsey, Nanuet, Mahopac, Haverstraw and Tarrytown.
Motorists are urged to avoid flooded roadways and never drive through standing water. Flooding is most likely in low-lying and poor-drainage areas, as well as near rivers and streams.
