A heat warning from Environment Canada is in effect for the weekend.
A very warm and somewhat humid airmass will be in place across portions of Northwestern Ontario for the next few days. Daytime highs are expected to reach 30 degrees today, tomorrow and possibly Sunday.
In addition, overnight lows will only fall into the upper teens, thus providing little relief from the hot weather.
While extreme heat can put everyone at risk from heat illnesses, health risks are greatest for:
•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
Drink plenty of liquids especially water before you feel thirsty to decrease your risk of dehydration.
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, such as heat stroke or heat exhaustion.
