A Severe Thunderstorm Watch is in effect for the Kenora and Grassy Narrows areas.
Environment Canada warns that clusters of thunderstorms with high winds are expected to develop this afternoon or tonight, with up to 90 km/h winds. The storms are expected to begin near the Manitoba border and move eastward.
Environment Canada adds that strong wind gusts can toss loose objects, damage weak buildings, break branches off of trees and overturn large vehicles, so residents should be prepared for severe weather.
Take cover immediately if threatening weather approaches, and stay in shelter for at least 30 minutes past the final roar of thunder to ensure the storm has passed your area.
