A strong cold front moving into Maine will bring rain and potentially severe thunderstorms with flash flooding this afternoon.

Multiple rounds of thunderstorms with very heavy rainfall are expected in Maine after noon, according to the National Weather Service. Heavy rainfall could cause flash flooding, particularly in areas with poor drainage.

Brandon Mitchell of the National Weather Service in Gray said the primary concern with today’s storms will be the flash flood threat and winds, which will be strong as the storms move toward the coast during the afternoon. Up to an inch of rain is expected in most southern areas, with high amounts expected in areas where the storm is especially intense.

“There is a slight chance of tornadoes before the main line of the storm gets to the coast,” Mitchell said.

A flash flood watch is in effect from noon through this evening for portions for York County and parts of New Hampshire.
