Special Weather Statement
Issued: 5:10 AM Dec. 19, 2025 – Environment and Climate Change Canada
Rain tonight, followed by gusty winds and rapidly falling temperatures Friday. What: Total rainfall amounts of 10 to 20 mm. Rapidly falling temperatures resulting in surfaces becoming icy and slippery. Westerly to northwesterly winds gusting 60 to 80 km/h. When: Tonight through Friday night. Additional information: Rain will overspread the area tonight before changing over to flurries through the day on Friday as temperatures rapidly fall below the freezing mark. This will be the result of a strong cold front passing through the area. Southerly winds will abruptly become westerly to northwesterly upon the passage of the cold front with gusts of 60 to 80 km/h. Winds are expected to ease through Friday evening, except after midnight for far eastern Ontario. Flurries and snow squalls off Lake Huron and Georgian Bay are also expected behind the front. Roads and walkways may become icy and slippery. Travel may become difficult at times. Local utility outages are possible. For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources office. Visit Ontario.ca/floods for the latest details. ### Please continue to monitor alerts and forecasts issued by Environment Canada.

Yellow Watch - Snow Squall
Issued: 4:50 AM Dec. 19, 2025 – Environment and Climate Change Canada
Lake effect snow off Lake Huron and Georgian Bay expected Friday. What: Local snowfall amounts of 10 to 20 cm. Reduced visibility in heavy snow and blowing snow. When: Friday morning through Friday night. Additional information: Lake effect snow off Lake Huron and Georgian Bay will quickly develop Friday morning as temperatures rapidly drop in the wake of a strong cold front. Westerly to northwesterly winds gusting 60 to 80 km/h will result in blowing snow. The combination of heavy snow and blowing snow may result in near zero visibility at times. As the winds will shift from westerly to northwesterly through the day, lake effect snow bands are not expected to persist over a given location for a prolonged period. As a result, reduced visibility in heavy snow and blowing snow will be the primary hazard as opposed to snowfall accumulations. Lake effect snow should weaken through Friday night. ### Travel may be hazardous. Visibility may be suddenly reduced to near zero at times. 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.
