The Caribou radar (KCBW), 68 km away, was scanning. The volume nearest the first event began at 21:05 UTC.
4 thunderstorm wind, 1 tornado. Local standard time, as filed.
Several trees were snapped or uprooted along Grand Lake Road...west of Huber Road...by wind gusts estimated at 65 mph.
An EF0 tornado snapped or uprooted numerous trees in a remote portion of northern Penobscot county near Shin Pond. Some trees were snapped near their base while the majority were snapped further up the trunk...with several of the trees around 20 inches in diameter and 100 feet tall. Based on the storm survey...it was determined that the tornadic circulation generally remained just above the surface along much of its path...affecting mostly the tree tops. The most extensive tree damage occurred along...and just north of...Grand Lake Road between Scraggly Lake Road and Flemming Brook.
Numerous large trees were toppled from Shin Pond to Hay Lake by wind gusts estimated at 65 mph.
A tree was partially toppled on to powerlines by wind gusts estimated at 60 mph. The tree hung on the powerlines and caught fire. Two sisters and their stepfather went outside to look at the buring tree. While they were standing there...the tree completely fell bringing down the powerlines. The powerlines fell across the girls legs burning them. The stepfather received arm and shoulder injuries after being thrown by a jolt of electricity while attempting to remove the powerline from the girls. All three were transported to the hospital. The injuries were determined to be indirect.
Numerous trees were toppled on Station Road by wind gusts estimated at 60 mph.
