NEW YORK CITY - The National Weather Service has issued a severe thunderstorm watch in the NYC area on Sunday.

"We're going to see a lot of strong thunderstorms firing up here too," FOX 5 NY's Audrey Puente said. "We do anticipate storms and showers to move into the city as we go closer to 8 p.m."

The heavy rainfall tonight may lead to isolated to scattered instances of flash flooding, the National Weather Service said. Additional heavy rainfall is possible Monday afternoon and evening. Flash flooding is also swamping parts of Connecticut, FOX Weather reports.

Storms are also dumping locally heavy rain in some areas, raising concerns for flash flooding across the region.

Connecticut severe flooding

Significant flash flooding was reported in portions of western Connecticut on Sunday, prompting several road closures and water rescues in cities such as Stamford and Danbury. There were even reports of a mudslide in Danbury, which caused a major gas leak and forced evacuations in the Woodland Hills Complex, according to the NWS.

A Flash Flood Emergency was later issued Sunday afternoon for central Fairfield and northern New Haven counties in Connecticut as rainfall rates approached 2-3 inches per hour on top of the 4-8 inches of rain that had already fallen since Sunday morning.

The FOX Forecast Center said scattered thunderstorms will increase in coverage through the afternoon and evening across the Northeast and mid-Atlantic. The most intense storms will pose a risk of damaging wind gusts up to 70 mph and hail up to the size of ping pong balls (1.5 inches in diameter).

Any severe storms are expected to come to an end by late Sunday evening. However, a renewed severe weather threat looms for Monday in many of the same areas being threatened Sunday.
