Active AlertsCanoe Landing Park, ON

A winter storm is possible beginning on Sunday.

What:
Snowfall amounts of 20 to 30 cm. Locally higher amounts are possible.
Visibility near zero at times in blowing snow with winds gusting to 50 km/h.

When:
A local lake effect snow band beginning early Sunday morning is possible.
Widespread snow beginning Sunday afternoon and ending Sunday night.

Additional information:
Lake effect snow driven by easterly winds off Lake Ontario may develop early Sunday morning, producing localized snowfall and reduced visibility.

By Sunday afternoon, snow is expected to become more widespread as a broader system moves into the area. As this occurs, lake enhancement is likely, which will lead to locally higher snowfall amounts in certain areas.

The exact placement and intensity of the heavier snowfall remains uncertain at this time.
