Environment Canada has issued a snowfall warning for Thunder Bay as a series of weather systems bring heavy snow and hazardous conditions to the region through Saturday, April 4, 2026. Residents are being advised to prepare for difficult travel as the storm impacts the start of the Easter long weekend.
The current weather alert, which was first issued on Wednesday, April 1, forecasts total snowfall accumulations of 10 to 20 cm from the initial system. A second weather system is expected to move into the area on Saturday morning, potentially adding another 10 cm of snow. In total, the region could see between 20 and 35 cm of snow between Thursday and Sunday.
According to Trudy Kidd, a meteorologist with the federal agency, the heaviest snow was concentrated overnight into Friday morning. Beyond the snowfall, wind chill values between -10 and -11°C are creating cold and hazardous conditions for anyone heading outdoors.
Local authorities warn that roads and walkways will likely be difficult to navigate, and road closures are possible throughout the area. The storm is also affecting surrounding communities in northwestern Ontario, including Atikokan, Beardmore, Cloud Bay, Geraldton, Marathon, Nipigon, and Wawa.
With many residents traveling for the holiday, the Canada Border Services Agency is urging travelers to allow extra time for their trips and to check the latest road reports before heading out. Motorists are encouraged to exercise caution, as visibility may be reduced in heavy snow and blowing snow.
