Intensifying low pressure tracked toward the Maine coast through the night of the 3rd into the morning of the 4th. The low then tracked across Downeast areas to New Brunswick through the remainder of the 4th. Snow developed during the evening of the 3rd. The snow then mixed with...or transitioned to...sleet which persisted into the early afternoon of the 4th. Warning criteria snow and sleet accumulations occurred during the early morning hours of the 4th. Storm total snow accumulations generally ranged from 4 to 8 inches along with 1 to 3 inches of sleet. However...snow accumulations of 6 to 10 inches occurred across northwest Aroostook county where more precipitation fell in the form of snow.
Strong onshore winds...large breaking waves along with an astronomical high tide combined to produce minor coastal flooding around the time of high tide during the early morning hours of the 4th. Rocks were washed onto Seawall Road due to the flooding.
The weight of sleet and snow from this storm and other recent storms led to significant build-ups on the roofs of many structures. During the next several days structural collapses were reported at several locations across northern Maine. Most of the structures were barns. However...a band shell collapsed in Fort Fairfield in northeast Aroostook county. A private aircraft hangar also collapsed at the Greenville Airport in central Piscataquis county. The collapse destroyed the hangar and damaged the plane inside.
