MONTREAL – Enivronment Canada issued a heat warning Monday morning for Montreal and surrounding areas including, Châteauguay, La Prairie, Laval, Longueuil and Varennes.
With humidex values expected to reach 40, officials are warning residents to stay hydrated by drinking plenty of liquids.
They’re also reminding people not to wait to be thirsty before reaching for that water bottle as thirst is not a good indicator of dehydration.
Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses.
Environment Canada said that while anyone can suffer from heat exhaustion or heat stroke certain segments of the population are more at risk, including:
- infants and young children;
- people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses;
- people who work or exercise in the heat;
- homeless people; and
- people without access to air conditioning
A cold front overnight is expected to improve conditions and provide relief from the high heat and humidity.
