About lightning in Vermont
Vermont’s thunderstorms are summer afternoon events, firing along cold fronts and lifting over the Green Mountains. Terrain and forest can hide a building storm until it is close. The brief active season runs June through August. When a storm does develop, tracking the nearest strike and whether it is approaching gives a clearer warning than thunder carrying across the valleys.
