Coastal Flood — Sagadahoc, Maine

2022-01-17 · Sagadahoc, Maine

Event narrative

The astronomical tide in Portland of 9.6 feet combined with a storm surge of 3.1 feet at high tide to produce a 12.7 foot (MLLW) storm tide during the late morning hours. Flood stage in Portland is 12.0 feet (MLLW). The tide remained above flood stage for a full three hours and 26 minutes at the Portland tide gage. The intense easterly winds and high storm tides led to closed roads due to large battering surf and water flooding inland tidal areas. Flooding was reported on Washington Street in Bath, Route 209 Near Popham Beach in Phippsburg was closed and Williams Rd. in Georgetown was inundated and closed.

Wider weather episode

Low pressure rapidly intensified into a strong storm (980 mb) and tracked over western New England on the morning of January 17th. This allowed for a strong easterly flow to develop as the system passed to our west. Winds peaked around the time of high tide with gusts over hurricane force reported across the Gulf of Maine. Astronomical tides were marginal during the event, however very high storm surge values tied for the eleventh highest of all-time during the midday high tide cycle on the 17th. The surge and large waves caused minor flooding across York and Cumberland counties.
