Reported by: NWS Storm Survey

After surveying damage from a severe thunderstorm, the National Weather Service confirmed that a thunderstorm macroburst caused most of the damage in the Town of
St. Albans.
Winds estimated at 80 to 90 mph snapped or uprooted hundreds of trees across sections of St. Albans near the north end of Indian Pond.  The strong winds were accompanied by heavy rain and hail.  The hail and wind also damaged crops in the area.  Dozens of utility poles were brought down by the falling trees.  Some of
the hardest hit roads included Ballard Road, Papoose Lane, Dinsmore Drive, Ripley Road, Luckman Road, and a small area to the east of Todds Corner Road.
