An area of low pressure rapidly intensified while tracking from the southeastern states to the southern New England coast from the 15th to the 16th. A tight pressure gradient developed between the low and high pressure centered over eastern Canada which also blocked the northern movement of the low. The intense low slowly drifted east from the 16th through the 19th while high pressure remained across eastern Canada. The storm had many impacts on the region including strong damaging winds...heavy rain with urban and small stream flooding and coastal tidal flooding. These impacts were most significant across Downeast areas...particularly near the coast. In addition...the storm brought locally heavy snow to some higher elevations of northern and northwest Maine.
The tight pressure gradient supported strong east to northeast winds across mostly central and Downeast portions of the region through the 16th and 17th. Disturbances rotating around the main low contributed to several surges of strong winds over the course of the event. Winds gradually diminished during the 18th and 19th...though gusty winds still lingered during this time particularly near the Downeast coast.
Damaging winds occurred across all of Downeast Maine...particularly near the coast where some wind gusts exceeded 70 mph. Damaging winds extended inland to central Piscataquis...central Penobscot and northern Washington counties. The combination of strong winds and saturated ground from the heavy rains which accompanied the storm and the spring thaw contributed to the uprooting of numerous trees with many other trees snapped and broken. Several trees fell on structures and vehicles causing damage. Other trees and branches brought down powerlines when they fell...with power poles also snapped and toppled due to the strong winds which contributed to thousands of power outages. Fallen trees and power lines also blocked roads.
The combination of astronomical high tides...amongst the highest of the year...along with persistent strong onshore winds and large waves contributed to coastal flooding during high tide cycles starting on the evening of the 16th and continuing through the evening of the 19th. During high tides...overwash flooded some coastal roads resulting in road closures. Debris was washed onto roads with some roads also damaged. A causeway connecting the mainland with Deer Isle was closed several times during the event due to overwash and flooding.
The storm also brought heavy rain to the region. The heaviest rains occurred across central and Downeast areas...along with the favored upslope areas of Piscataquis county. Rainfall totals across central and Downeast areas generally ranged from 2.50 to 4.00 inches...with local totals in excess of 5.00 inches. Across Piscataquis county...rainfall totals generally ranged from 2.50 to 4.00 inches with local totals approaching 5.00 inches. The heavy rain contributed to rapid rises on smaller rivers and streams across the region some of which overflowed onto surrounding low land areas. The small river and stream flooding caused some road closures. Urban and poor drainage flooding also occurred which led to additional road closures and contributed to basement flooding. Mainstem rivers also rose during this time but crested below flood stage.
Enough cold air was in place to support an interval of heavy snow during the early stages of the event across the higher terrain of Piscataquis county and northern Somerset county. Snowfall totals across some higher terrain areas ranged from 8 to 12 inches...with local totals in excess of 12 inches. Lesser snow acumulations occurred at lower elevations.
