Flash Flood in Coos County, New Hampshire

Flooding and washout on NH-135 or Knot Hole Road in Whitefield.

On July 10th the remnants of Tropical Storm Beryl phased with a low pressure system out of the Great Lakes to bring multiple rounds of heavy rainfall to northern New England, including Maine and New Hampshire. The previous 3 days had brought a swath of heavy rain just north of the White Mountains, saturating the ground and making it ideal for runoff. During the roughly 36 hour period, 3 to as much as 5 inches of rain fell across northern New Hampshire and Western Maine Mountains. This led to significant flash flooding around Littleton New Hampshire, and sporadic flash flooding eastward into Maine. A few trees were also downed to severe wind gusts.
