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. This information can also be found on our website at www.weather.gov/gyx. For reference... Straight-line winds are generally any wind that is not associated with rotation...used mainly to differentiate them from tornadic winds. $$ Kimble
