Accumulating snow likely on Sunday. What: Snowfall amounts of 5 to 15 cm. When: Beginning Sunday morning and continuing into Sunday night. Additional information: A low pressure system could bring significant snowfall to parts of southern Ontario on Sunday. Confidence remains low with respect to the strength and track of this weather system, and as such the areas affected and snowfall amounts may change. Snowfall warnings may be required. Motorists should expect difficult winter driving conditions and adjust travel plans accordingly. Poor weather conditions may contribute to transportation delays. Installation of winter tires should be considered prior to Sunday. ### Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
