The National Weather Service in Gray ME has confirmed that straight
line wind damage occurred near Conway in Carroll County New
Hampshire on July 1, 2017.

National Weather Service meteorologists surveyed damage along the
northern end of Conway Lake in Conway, New Hampshire. Eyewitness
reports and visible damage was consistent with straight line winds
from a downburst which occurred over the northern end of the lake.

The most significant area of damage was on the northern shore of
Conway Lake where several trees were snapped and uprooted, being
blown onshore. Several more trees were snapped and uprooted on a
small island near the northern end of the lake. Eyewitnesses
reported heavy rain and golf ball sized hail falling immediately
prior to the onset of the strong winds. This is consistent with
downburst winds flowing out of the downdraft region of a severe
thunderstorm. The downburst was likely centered over the northern
portion of the lake, with winds blowing outward toward and along
the lake shore. These winds were as strong as 85 MPH which is
consistent with the damage to trees noted along the lake shore.
