The National Weather Service has issued a tornado watch until 5 p.m. today in all five borough of New York City, as well as parts of New Jersey and Long Island.
A cold front is moving into the area this afternoon, bringing with it heavy rainfall, thunder and strong winds that could hit 75 miles per hour. The agency said they expect to see minor flooding in poor drainage areas, and in some cases, a flash flood threat.
A tornado watch is less severe than a tornado warning, and means that weather conditions are favorable for a tornado.
