What the reports say
Written by National Weather Service staff at the time of the event · public domain
A cold front moving across the area generated severe thunderstorms which produced large hail and gusty winds. Baseball-size hail lasted for up to 20 minutes in Deep River causing hundreds of thousands of dollars in damage. The hailstones broke hundreds of windows in buildings and automobiles, tore holes in roofs, dented siding and automobiles, and ruined gardens. Some automobiles were totalled. In one historic building, the hail broke 25 windows, including a 100-year curved window. Thirty-two windows were smashed in an elementary school and its roof was damaged. Most of the damage was covered by insurance.
