UPDATE: Severe thunderstorm warning over
Environment Canada has ended all severe thunderstorm warnings and watches for Sarnia-Lambton County.

Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Intense lightning is likely with any thunderstorm that develops
The Office of the Fire Marshal and Emergency Management recommends that you take cover immediately if threatening weather approaches.
