Due to the blizzard warning and state of emergency issued by Gov. Gina Raimondo, the Providence Journal is reporting that -- "Fleetwood Mac: Mick Fleetwood, Stevie Nicks and crew are scheduled to play at the Dunk on Wednesday night. Their stage crew traveled to Providence Monday and the performers are due to drive from New York City to Rhode Island Wednesday but if the state of emergency isn’t lifted by early Wednesday, the concert will be pushed to Thursday."

So depending on the severity of the storm and whether or not travel is allowed on the roads, the Fleetwood Mac show scheduled for Wednesday, may be pushed to Thursday. Please check with the Dunkin' Donut Centre before heading out on Wednesday. They will likely post updates to their facebook page as well.
Update: 10pm ET - The show is still scheduled as planned.
