The Tri-State area is in the path of severe weather for the third time in about six weeks, as a slow-moving storm system from the west threatens more flash floods, lightning, heavy rain and potentially damaging winds.
Much of the area is in line for 1 - 2 inches of rain, so flash flood watches are in effect Thursday into Friday. New York City has issued a travel advisory.
A flash flood watch has been issued for all five boroughs of New York City, plus Dutchess, Nassau, Orange, Putnam, Rockland, Sullivan, Westchester and Ulster counties in New York from Thursday afternoon through Friday morning.
The rains were expected to arrive in New Jersey at around 2:30 p.m. then crawl eastward, arriving in New York City late in the evening — between 8 p.m. and 11 p.m.
The storm could linger in the region for as long as 48 hours.
Its slow pace is what has forecasters most concerned. The longer the system hovers over the Tri-State area, the higher the flood risk will be, particularly in areas still recovering from record-breaking rainfall from Ida and Henri this summer.
