Northwestern Ontario faces a winter storm from Tuesday to Thursday, with up to 30 cm of snow and dangerous whiteout conditions expected.
Winter Storm Watch Issued Across Northwestern Ontario
Alert Covers Widespread Communities
A winter storm watch is now in effect for much of northwestern Ontario, as Environment and Climate Change Canada warns residents of significant snowfall. The advisory, issued Monday morning, affects communities from Thunder Bay to White River, including Atikokan, Marathon, Geraldton, Nipigon, and several rural corridor regions expected to see the heaviest impact.
Storm Timeline and Expected Conditions
The storm system is forecast to arrive Tuesday evening and continue through Thursday, moving west to east across the region. Forecasters expect between 15 and 30 centimetres of snowfall, though some areas north of Lake Superior may see totals exceeding 30 centimetres. Strong northerly winds are expected to intensify conditions, producing blowing snow and sudden drops in visibility.
Communities Along the Impact Path
The watch covers a wide swath of territory, including Thunder Bay, Kakabeka Falls, Beardmore, Longlac, Marathon, Schreiber, Manitouwadge, Hornepayne, and surrounding rural areas. Environment Canada notes uncertainty over the storm’s exact track, meaning the corridor of heaviest snowfall could shift as the system approaches.
Risks to Travel and Daily Activities
Officials warn that roadways, highways, and walkways may become hazardous as the snow accumulates and winds create whiteout conditions. Drivers and pedestrians could face near-zero visibility at times, raising the risk of road closures and delays. Residents are urged to reconsider travel plans, particularly between Tuesday night and Thursday morning.
Public Safety Measures and Preparedness
Environment Canada advises the public to prepare for rapidly changing conditions by monitoring updates, securing emergency supplies, and allowing extra travel time. With the potential for disruptions across the region, authorities stress the importance of caution as the storm system moves through.
