A Dave Matthews Band concert scheduled for Tuesday night at Northwell at Jones Beach Theater has been postponed because of forecasts of severe thunderstorms, flooding and potential tornadoes, the band announced.

"In consultation with the venue, local and state authorities and an official NWS Tornado watch," the band said in a post on Instagram," we are sorry to report that tonight's show at Jones Beach will be postponed."

Tickets will be honored for the rescheduled concert, which will take place July, 29, the band said in a social media statement.

Nassau County and New York City are under a tornado watch until 9 p.m. Tuesday. The National Weather Service warned of potential flood floods.

Gusts of up to 60 mph could down power lines and trees, particularly in the Huntington Station area, the weather service said in an Tuesday afternoon alert.
