April 28 (Bloomberg) -- Powerful thunderstorms, soaking rain and high winds are possible in New York City, New Jersey and parts of Connecticut until about 4 p.m., according to the National Weather Service.
Storms have delayed air traffic across the U.S. Northeast.
A severe thunderstorm watch and flash flood watch has been issued for the city as well as parts of Long Island, New Jersey and Connecticut, according to the weather service in Upton, New York. Wind gusts as intense as 60 miles per hour (97 kilometers per hour) are possible, said Joe Pollina, an agency meteorologist.
“The primary threat is damaging winds,” Pollina said. “There is also a flash flood watch out because some of these storms can produce some heavy rainfall. There could be an isolated tornado.”
Governor Andrew Cuomo activated the state emergency operations center to monitor the weather.
A tornado warning, meaning one of the storms may have formed, was issued until 12:15 p.m. for Passaic, Essex and northern Bergen counties in New Jersey and for Rockland and Orange counties in New York. Pollina said the weather service is investigating.
Flights to New York, Baltimore, Washington, Philadelphia and Newark were being delayed until storms have passed, according to the Federal Aviation Administration website. Almost 800 flights were canceled, according to the FlightAware tracking service.
An outbreak of tornados across the U.S. yesterday killed more than 200 people, mostly in Alabama, and left a trail of damage across at least 21 states. Tornado watches, meaning the storms may develop, stretch today from Maryland to Georgia and include Washington and Baltimore.
