Caribou, Maine – Flood concerns across northern and eastern Maine have sharply eased, with river ice breakup reducing the immediate threat of ice jam flooding heading into midweek.
According to the National Weather Service in Caribou, the risk of ice jams has ended for most rivers across eastern and northern Maine, with only limited risk remaining along the St. John, Allagash, and Aroostook rivers. Ice in northern basins remains about 60% to 75% intact but continues to weaken in place, allowing for gradual and controlled movement.
Snowpack across the region is now well below normal, especially across the Central Highlands and Downeast areas where bare ground is widespread. Northern zones still report some lingering snow cover, particularly west of Route 11, but snow water equivalent values remain low, reducing runoff potential.
River flows are expected to stay near or slightly below normal levels through midweek. Warmer temperatures and below-average precipitation will further limit rapid snowmelt or sudden rises in water levels.
Residents near rivers should continue to monitor conditions, especially in northern valleys where isolated ice movement remains possible. Additional updates may be issued if river conditions change.
