A Heat Warning has been issued by Environment Canada for all of Southern Manitoba ahead of what will more than likely be the hottest and most humid days of the Summer, so far, on Thursday and Friday.

"Humidex values will reach 40 for Thursday and Friday," noted the alert. "Daytime highs at or above 32 degrees Celsius, with overnight lows above 16 degrees Celsius are also expected."

According to the forecaster, temperatures will increase further Thursday and Friday over southern Manitoba as an upper level ridge moves over the area, bringing extreme daytime temperatures and humidex with little overnight relief.

"A slight reprieve is likely beginning late Friday into the weekend as the warmest air shifts southward, though temperatures will remain well above seasonal into early next week," explained the Warning.

Extreme heat can affect everyone’s health. The health risks are greater for older adults, infants and young children, pregnant people, people with physical and/or mental illnesses, and people with disabilities or mobility issues.

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 regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.

If you are in an overheated area, seek a cool place such as a tree-shaded area, splash pad, misting station, or air-conditioned spot like a public building. Limit direct sun exposure. Shade yourself by wearing a wide-brimmed, breathable hat and/or an umbrella.
