Environment Canada has issued a heat warning for the Guelph, Erin and Southern Wellington County areas beginning today (July 11) lasting into Thursday, July 17:

Daytime highs of 29 to 32 degrees Celsius and a humidex of 35 to 40 are expected with overnight lows of 19 to 23 degrees Celsius, providing little relief from the heat. The temperatures and humidex will meet or be extremely close to heat warning criteria, with the hottest day being Saturday. A shift in the weather pattern on Thursday will likely end this multi-day period of heat and humidity.

Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.

Protect yourself and others by:

• Knowing the forecast and being on the lookout for heat warnings
• Having a plan to take breaks from the heat
• Remembering that children, the elderly and those with chronic conditions are at higher risk of heat-related illness
• Staying hydrated by drinking plenty of water or juice
• Never leaving people or pets inside a parked vehicle
