A heat warning remains in tact across Chatham-Kent, as humidex values are expected to reach 43 on Monday.
“This will be the most significant heat event in the past few years, forecaster say.
“A cold front is forecast to pass through southern Ontario this afternoon ushering in a slightly cooler and less humid air mass. However, daytime highs are still expected in the low thirties in the next 2 days and overnight low temperatures in the high teens, providing some relief from the extreme heat of the weekend.”
The high heat and humidity could return on Wednesday.
“Daytime highs again will be near mid thirties with humidex near mid forties. Overnight low temperatures are expected to be in the low twenties, except high teens in some rural areas, providing little or no relief from the heat,” Environment Canada officials say.
A cool down is expected by Friday with the passage of a cold front.
“Never leave people or pets inside a parked vehicle. 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.”
Forecasters say to watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
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.
