A severe thunderstorm and associated microburst reached the western shore of Sebago Lake just after 4pm.  The damaging winds downed 80 to 100 trees...some uprooted and others snapped.  Most of the trees were softwoods while a few were hardwoods. About fifteen structures were damaged along with ten vehicles.  One fatality occurred when a tree fell on an occupied vehicle.  The most significant damage occurred within a one mile path width and within a quarter mile of the western shore of Sebago Lake. Sporadic damage occurred beyond this.  This storm would continue to produce
additional wind damage as it moved east of Sebago Lake later in the afternoon.
