Another heat warning has been issued across Chstham-Kent, as humidex values reaching 42°C are expected for the next four days.
“A hot and humid tropical air mass will affect Southwestern Ontario beginning Friday,” Environment Canada officials stated.
“The heat and humidity will last through the weekend to at least Monday. Afternoon temperatures will reach the low to mid thirties. Humidex values will reach the low forties each afternoon. Temperatures overnight will remain in the low to mid twenties, providing little relief from the heat.”
Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index to approach the high risk category, forecasters say.
“Slightly cooler and less humid conditions may arrive on Tuesday,” Environment Canada officials stated.
“Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions. Never leave people or pets inside a parked vehicle. When it’s hot eat cool, light meals.”
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, forecasters say.
“Please continue to monitor alerts and forecasts issued by Environment Canada,” forecasters added.
