Metro Montréal - Laval issued by Environment Canada

Weather conditions in these regions are favourable to the development of severe thunderstorms. Some of these thunderstorms could produce large hailstones, high winds, heavy rain and intense lightning. People in these regions should take the necessary precautions and listen for subsequent weather warnings, as severe weather warnings may be issued if severe weather becomes imminent.

Thunderstorms are already affecting certain parts of Western Québec. As a result of daytime heating, other more intense thunderstorms will develop and could become severe in some areas.
