Heat Warning in effect for:

  • Barrie - Collingwood - Hillsdale

Humidex values reaching 40°C are expected.

A warm and humid night tonight, then hot and humid Tuesday.

Hot temperatures were delayed today due to extensive cloud cover and some shower activity. It is still expected to be warm and humid tonight with lows above 20°C.

On Tuesday, more sunshine is expected in most places. This should allow for maximum afternoon temperatures to reach close to 31°C with humidex values near 40°C. Overnight low temperatures Tuesday night will be in the low twenties providing little relief.

A cold front will bring cooler temperatures on Wednesday with highs of just 24°C or 25°C forecast.

The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.

Check on older family, friends and neighbours. Make sure they are cool and drinking water.

Never leave people or pets inside a parked vehicle.
