Heat conditions - afternoon to late evening.

Maximum temperatures of at least 30 degrees and high humidity levels are expected over Southwestern Quebec for the rest of the afternoon and early this evening. In these areas, humidex values will exceed 40. Overnight lows slightly above the 20-degree mark will offer little relief.

While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for - older adults - infants and young children - people with chronic illnesses such as breathing difficulties, heart conditions or psychiatric illnesses - people who work in the heat - people who exercise in the heat - people without access to air conditioning and - homeless people.

Heat illnesses include heat stroke, heat exhaustion, heat fainting, heat edema (swelling of hands, feet and ankles), heat rash and heat cramps (muscle cramps).

Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
