Strong southwesterly winds gusting near 90 km/h are expected this afternoon and early this evening, with higher wind gusts possible in thunderstorms. These strong winds are associated with a cold front that will track over the area late this afternoon and early this evening.
Slightly weaker northwest winds gusting to 70 km/h are also expected this evening after the cold front passes. Winds will then diminish overnight.
Damage to buildings, such as to roof shingles and windows, may occur. Loose objects may be tossed by the wind and cause injury or damage.

Severe Thunderstorm Watch

Thunderstorms are expected to develop ahead of a cold front beginning this afternoon. Wind gusts up to 100 km/h will be possible.
These thunderstorms will move through the area by early evening.
Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Remember, severe thunderstorms can produce tornadoes. Be prepared for severe weather. Take cover immediately, if threatening weather approaches. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
