Low pressure taking shape over the Southern Plains and Lower Mississippi Valley on Christmas Day intensified into a nor'easter as it moved into the Tennessee Valley on the 26th, passing just south of Long Island the morning of the 27th and then moving to Nova Scotia on the 28th. This system brought strong east winds to the region the 26th into the morning of 27th, which resulted in 3 to 5 feet of storm surge and widespread minor to moderate coastal flooding along the coast.
