The warm and humid air mass over Southern Quebec will persist until Thursday. The combination of temperatures and humidity levels will give humidex values near 40 over these regions early this evening and humidex values near 35 Thursday. 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. Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration.
