If you are planning on leaving your room today, you may want to think twice: the National Weather Service has issued a tornado warning for New Haven County (that’s us), along with much of Connecticut and parts of New York and New Jersey.

According to this map from the National Weather Service, there’s a 5 to 10 percent chance a tornado will touch down in New Haven sometime day. The NWS is also predicting showers and thunderstorms likely through 1 a.m. today.

A tornado’s already touched down today in Queens and Brooklyn, according to the New York Daily News, and rain has delayed the U.S. Open semifinal. The tornado warning remains in effect until 9 p.m.
