Authorities have issued a flash flood warning for New York City, parts of New Jersey and western Long Island as heavy rainfall, thunderstorms and strong winds swept across the region, raising the threat of widespread flooding and travel disruptions.

Weather officials warned that intense downpours could quickly overwhelm drainage systems, flood roads and affect low-lying areas. The flash flood warning remained in effect through Monday morning, while a broader flood watch was issued for New York City and northern and central New Jersey until the evening.

Forecasters also declared a First Alert Weather Day, citing an elevated risk of flash flooding and severe thunderstorms. Moist and humid air moving into the region is expected to produce rainfall rates of one to three inches per hour, with total rainfall forecast between one and three inches. Some isolated locations could receive even higher amounts, significantly increasing the risk of flooding.

In response to the severe weather threat, New York City Emergency Management activated its Flash Flood Emergency Plan. City crews were deployed to clear storm drains and catch basins in flood-prone neighbourhoods, while emergency teams were placed on standby to respond to flooded streets, fallen trees and stranded motorists.

Officials warned that severe thunderstorms could also generate damaging wind gusts, increasing the possibility of power outages and hazardous driving conditions throughout the day.

Meanwhile, a High Surf Advisory was issued for beaches south of New York City and across Long Island, where waves were expected to reach between six and ten feet. Authorities also warned of a high risk of dangerous rip currents and urged residents and visitors to stay out of the water until conditions improve.

Temperatures were expected to remain in the low 80s under mostly cloudy skies. Weather experts forecast that storm activity would gradually weaken by Monday night, bringing an improvement in conditions.
