The episode as NWS GYX wrote it up.
An early season Nor'easter developed and moved into the Gulf of Maine early on the 14th. This system produced a prolonged period of gale force winds and building seas.|In addition, very high astronomical tides from a super moon combined with the low pressure system to produce minor coastal flooding across isolated locations in southwest Maine. The tide in Portland Harbor topped out right at its 12 foot flood stage, resulting in very minor flooding of side streets along the wharfs. In Biddeford, very minor flooding occurred along side Granite Point road.
