Heat warning issued for Toronto and GTA

On Monday, the daytime high hit 32 C, but felt more like 41 with the humidity, according to Environment Canada weather data.

In addition to the severe thunderstorm watch, Chatham-Kent and Windsor-Essex are still under a heat warning.

High temperatures are looking to stick around for a few days this week, as Environment Canada has issued heat warnings for parts of the province.

A heat warning is issued for a period of maximum highs reach near 29 C or higher and when minimum overnight temperatures near 14 C or higher.

Temperatures will remain in the high 20s for the rest of the week, with the only rain in the forecast expected on Saturday.

Environment Canada says temperatures are not out of the ordinary for this time of year, but warns extreme heat carries health risks - especially for young children, pregnant women, the elderly, those with chronic illnesses or anyone working or exercising outdoors.


Heat illness can cause swelling, rash, cramps, fainting, heat exhaustion, heat stroke and worsen certain health conditions.

Environment Canada said the temperatures should take a slight drop mid-week as an on-shore flow develops. Environment Canada is warning that the extreme heat is especially unsafe for young children, pregnant women, older adults and people with chronic illnesses.

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

And as always, drivers are warned to never leave people or pets inside a hot auto.

Residents are also encouraged to reschedule outdoor activities or plan them for cooler parts of the day.
