CARIBOU, Maine – A crisp, dry stretch will hold through Sunday across northern and Downeast Maine, but coastal hazards are building behind the scenes. The National Weather Service in Caribou warns that frost or a light freeze is expected early Saturday morning for inland towns, while the shoreline will remain slightly milder.
According to the National Weather Service Caribou office, a slow warming trend will follow through early next week as high pressure dominates the region. The next weather system tracks south of the Gulf of Maine beginning late Sunday, bringing increasing clouds and a chance of showers or periods of rain through midweek, especially Downeast.
Along the coast, the bigger concern will be marine impacts. High surf and dangerous rip currents are expected Monday through Wednesday, with wave heights of 10 to 12 feet possible from Mount Desert Rock to Jones Ground. Breezy east-to-northeast winds will persist, and while widespread coastal flooding is not expected, forecasters caution that beach erosion and hazardous surf conditions could occur at high tide.
Travel inland should remain mostly unaffected, though early morning frost could impact sensitive vegetation Friday night and Saturday morning. Residents are urged to protect outdoor plants and ensure pets and livestock have shelter. Coastal visitors should stay well back from the surf and never turn their back on the ocean.
