WEST CARLETON – What has been a very hot and dry July will continue through Monday Environment Canada says.

This weekend’s heat warning will stay in effect through Monday, July 27.

“Minimum temperatures tonight (July 26) will be 21 to 25 degrees Celsius, with overnight Humidex values in the low 30s, providing little relief from the heat,” Environment Canada released in a statement today. “High temperatures Monday are forecast to be 30 to 33 degrees Celsius. Humidex values near 40 are also expected on Monday.”

A cold front will pass through southern Ontario from west to east Monday evening, bringing in a cooler and less humid air mass for Tuesday.

“Hot and humid air can also bring deteriorating air quality and result in the air quality health index approaching the high risk category,” Environment Canada said. “Extreme heat affects everyone. The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.”
