Winter Storm Warnings for Northern Ontario

Thunder Bay – Weather – There is still some roar left in March as we head to the end of the month.

Winter storm warnings in effect for:

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

Heavy snowfall with blowing snow today and Tuesday.

An intensifying low pressure system will be tracking across Far Northern Ontario from the Prairies.

Snow will develop this morning over the Sandy Lake region and will reach Big Trout Lake and Webequie this afternoon.

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

Total snowfall amounts of 25 to 40 cm. Snowfall combined with winds gusting to 70 km/h producing blowing snow.

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