Quick Answer: Why Do Lights Flicker During A Storm

Changes in the voltage of the electricity coming into your home during thunderstorms are behind the flickering lights. When a power line takes a direct hit, lights can flicker as a lightning protection system built into the power grid activates. Like a surge protector, voltage is temporarily reduced and the lights dim.

Is it normal for lights to flicker during a storm?

The most common causes of blinking lights are trees and branches.
