Environment Canada issued a Heat Warning for Portage la Prairie as of 3:39 p.m. Thursday.

The warning was triggered as humidex values are expected to reach 38 degrees for the next three days.

Environment Canada says that extreme heat affects everyone; they suggest citizens watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions. Drink plenty of water even before you feel thirsty, and stay in a cool place.

Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
