Sagadahoc County Flood History

Coastal Flood — Jan 13, 2024

The second severe storm in a week���s time struck the northern New England coastline during the middle of January. An intense and rapidly deepening area of low pressure over the Great Lakes region (979 mb) combined the highest astronomical tides of the month to produce extreme flooding along the coast. Portland had its all-time storm tide, posting a record flood water level (records 1912-...

High pressure anchored to the north of Maine dammed low level cold air up against the mountains and allow...

Showers and thunderstorms developed along the boundary and moved eastward. Since the system as a whole showed very little forward progression, multiple rounds of showers and thunderstorms ended up moving across the same l...

Tropical Storm — Sep 16, 2023

Hurricane Lee was a category 1 hurricane as it traveled north through the eastern Gulf of Maine early on Saturday, September 16th, before it was reclassified as Post-Tropical Cyclone Lee during the morning hours. The storm center eventually made landfall near Long Island, Nova Scotia on the evening of September 16th and then again in New Brunswick later on Saturday night. Lee brought numerous w...
