Humidex Advisory for Southern Ontario

The change will be abrupt as we move from spring into summer. Very warm temperatures in the low thirties and high humidity will move humidex values to over 40C tomorrow and over the weekend. The advisory is for south central and southwest Ontario but values here in the east will approach 40C, or just below advisory criteria. Drink plenty of fluids and guard against the heat. Keep an eye on the very young, old and your pets as well.
