Winter Weather Update

Thunder Bay – WEATHER – Today will be a day of weather contrasts across the region. The hotspot in both Canada and Ontario this morning at +8 is Wawa. Ontario’s cold spot is Washaho Cree Nation at -16.

There are winter storm warnings in effect across much of Northern Ontario.

An intense low pressure system is tracking across far northern Ontario, with heavy snow, blowing snow, strong winds, and thundersnow accompanying it.

Snow will gradually taper from west to east by this evening. Heavy snow and easterly to northeasterly winds gusting to 70 km/h will result in significantly reduced visibility in blowing snow. Snowfall amounts may be lesser for locations southeast of Webequie as a result of potential mixing with ice pellets and freezing rain.

Winter storm warning in effect for:

  • Big Trout Lake – Kasabonika
  • Sachigo Lake – Bearskin Lake
  • Sandy Lake – Weagamow Lake – Deer Lake
  • Summer Beaver – Wunnummin Lake – Kingfisher Lake
  • Washaho Cree Nation
  • Webequie
  • Peawanuck

Rapidly accumulating snow will make travel difficult. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Take extra care when travelling in affected areas. Consider postponing non-essential travel until conditions improve.
