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. During a storm or bad weather, there may be high winds, lightning, rain, ice, etcetera, which can affect the trees and branches near power lines.
