Just when you thought it couldn’t get much hotter, Environment Canada has issued a heat warning for Windsor-Essex and Chatham-Kent.

Daytime high temperatures are expected to reach the low thirties today with the low temperature tonight in the low twenties.

Humidex values are likely to approach 40 C this afternoon.

The forecaster says showers during Saturday and Sunday may provide some relief from the heat over the weekend.

Cooler conditions are expected on Monday.

Drink plenty of water even before you feel thirsty and stay in a cool place.

Seek a cool place such as a tree-shaded area, swimming pool, shower or bath, or air-conditioned spot like a public building.

Never leave people or pets inside a parked vehicle.
