Stormy weather brings flash flooding threat to NYC area on Monday. Get the First Alert Forecast.
Stormy weather will return to the New York City area on Monday, bringing the threat of heavy rain and storms that may lead to flash flooding.
Because of that threat, Monday will be a First Alert Weather Day.
An increasingly humid airmass has settled into the Tri-State Area and will set the stage for rounds of heavy rain and storms Sunday night through Monday. Overnight lows will not get much lower than the mid 70s.
The tropical airmass in place will allow for prolific rates of rainfall, 1-2 inches per hour, at times. Rainfall rates like that could certainly lead to flash flooding, especially in northeastern New Jersey, which was pummeled last week by floods.
A Flood Watch in place for northern and central portions of New Jersey through 11 p.m. Monday.
The New York City Emergency Management Department says it has activated the city's Flash Flood Emergency Plan, which includes advanced inspecting and clearing of catch basins in flood-prone areas. Task forces are also on alert to respond to fallen trees and stranded vehicles.
A general 1-3-inch rainfall is expected across the area, with isolated higher totals likely.
Severe thunderstorms are possible as well, although the likelihood of them forming is not terribly high. The greatest hazards associated with any storms that develop would be torrential downpours and damaging winds.
A High Surf Advisory has been issued for all ocean beaches in New York for Monday. Waves could reach as high as 9 feet. A High Rip Current Risk is also in effect for all ocean beaches across the area through Monday.
Highs on Monday will be kept down by all the clouds and rain, only reaching the low 80s in most locations.
By Monday night, the rain and storm threat should come to an end. That will lay the foundation for a beautiful day on Tuesday, featuring more sunshine and a slight drop in humidity levels.
Storm chances and high humidity levels will then climb again for the rest of the week.
