Strong and severe storms moved through Maine on Sunday, causing damage and knocking out power. There was even a tornado warning in southern Aroostook County on Sunday afternoon, with reports of a brief funnel cloud in Sherman. That warning expired at 3:15 p.m. Sunday. Although radar indicated a tornado, there was no official confirmation as of early Sunday evening. That process could take a few days. There were numerous reports of damage from storms in the northern part of the state between Brownville and Millinocket.
