Heat Warning

THOMPSON – WEATHER – There are heat warnings out across much of Northern Manitoba. The heat will be amplified by smoke from forest fires in the region which could cause health issues for people with respiratory problems.

Heat Warning in effect for:

  • Leaf Rapids
  • Lynn Lake
  • Pukatawagan
  • Flin Flon Cranberry Portage and Grass River Prov. Park
  • Snow Lake and Herb Lake Landing
  • Nelson House
  • South Indian Lake and Amisk Prov. Park
  • Split Lake and York Landing
  • Thompson Thicket Portage and Pikwitonei

Environment Canada reports, “The heat wave continues in northern Manitoba.”

A period of day time high temperatures in the high twenties and low thirties with overnight low temperatures in the mid to high teens continues with the warmest days slated for today, Monday and possibly Tuesday. Additionally, diminished air quality associated with the smoke resulting from forest fires burning in the region may amplify health impacts resulting from the heat.

This heat wave is forecast to persist into Tuesday after which a high pressure area pushing down from the Arctic will cause temperatures to cool to more seasonal values.

It will be warm in the far north in Ontario as well
