Coastal Flood — Sagadahoc, Maine

2024-01-13 · Sagadahoc, Maine

Event narrative

The astronomical tide in Portland was 11.2 feet (MLLW) at 1205 pm. Flood stage is 12 feet (MLLW). The gale to storm force onshore winds produced a storm surge of 3.37 feet in Portland Harbor. The resulting storm tide topped out at 14.57 feet (MLLW) in the Forest City with the tide remaining above flood stage for two hours and 38 minutes.

The storm created significant damage to waterfront areas of Sagadahoc County due to both inundation flooding and over wash from large coastal swells that overtopped dunes and seawalls. At Popham Beach and Reid State Park, severe erosion occurred to the dune structure. In Georgetown, Williams Road, Indian Point Road, Kennebec Point Road, Bay Point Road and Mill Island Road were all flooded, docks and floats were significantly damaged by the waves. In Bath, Route 127 was closed due to deep inundation, keeping Georgetown cutoff until the water receded. Flooding was also reported in Bath on Commercial Street, along the waterfront and all low lying roads near the Kennebec River. In Woolwich, Route one was closed due to coastal inundation. Numerous roads were eroded in Edgecomb by the crashing surf. Flooding and debris were reported on Bailey Island.

Wider weather episode

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-present). Storm force southeasterly winds occurred along the coast with nearshore waves of 15 to 20 feet leading to wave run-up impacts along exposed areas, especially areas vulnerable to southeast swells. A flash flood warning was issued for Coastal Cumberland and York Counties prior to high tide due to rapidly rising ocean water and fresh waters as heavy rain accompanied a coastal front just prior to high tide.
