Thunderstorms with strong winds may develop in New York City today, dropping as much as 2 inches of rain and causing street flooding, according to the National Weather Service.
A flash flood watch has been issued for New York, parts of northeastern New Jersey and western Long Island as a warm front stalled over the area may become the catalyst for strong thunderstorms, said Joe Pollina, a weather service meteorologist in Upton, New York.
The thunderstorms may bring as much as 1 to 2 inches (2.5 to 5 centimeters) of rain in as little as an hour in isolated areas and send streams over their banks, according to the weather service. The area also has a 15 percent chance of damaging winds, according to the Storm Prediction Center in Norman, Oklahoma.
A severe thunderstorm developed today near Newton, New Jersey, about 60 miles west of New York, that was capable of dropping “quarter-sized hail” and producing 60-mph (97-kph) winds, according to the weather service. A number of trees were reported knocked down in Newton, as well as in eastern Pennsylvania, according to the storm center.
A flash flood warning was also issued from Scranton, Pennsylvania, to Monticello, New York, because of storms that may leave as much as 4 inches of rain across that area in about three hours.
The weather caused delays of as much as two hours for flights going to New York’s LaGuardia Airport, according to the Federal Aviation Administration. Flights to Newark International and Teterboro in New Jersey were experiencing delays of 30 to 45 minutes.
Pollina said the worst weather will probably occur later today and into tonight. There is also a chance of more thunderstorms tomorrow.
