An area of low pressure moved northeast from Massachusetts into Maine and New Hampshire on the morning of the 8th. The rainfall intensity increased during peak heating, with the heaviest rainfall from Nashua New Hampshire to Waterville Maine. Rainfall reports were highest across Cumberland and Androscoggin Counties in southern interior Maine ranging between 3 and 5 inches. After a break in the heavy rainfall, another round of scattered heavy rain showers developed in the late evening causing significant flooding in rural northern Franklin County along Rt 17.  Following a very wet July, the water table and streams were all elevated prior to the rains on August 8-9th. The storage for additional rain was limited, which lead to widespread impacts. Flooding was most notable across these locations with numerous flash floods as streams and soil conditions were already swollen.  Several streams came out of banks, as well as the Presumpscot River which reached minor flood stage.
