This from Environment Canada:
Special weather statement in effect for:
- Chatham-Kent – Rondeau Park
- Windsor – Leamington – Essex County
Very warm and humid conditions expected today into Tuesday.
Humidex values in the upper thirties to near forty are likely today and may occur Tuesday afternoon, with little relief from the heat overnight. It will be cooler near some lakeshore areas.
These conditions pose a health risk when you are not used to the heat.
Everyone is at risk from heat, especially older adults; infants and young children; and people with chronic illnesses.
You are advised to 1) drink plenty of cool liquids before feeling thirsty; and 2) keep cool by dressing for the weather and spending a few hours each day in a cool place.
