The air conditioner will be working overtime the next couple of days with sizzling temperatures expected in Toronto and much of southern Ontario.

A heat warning, which was issued by Environment Canada on Monday, remains in effect for parts of the GTA, including Toronto, as well as the Hamilton and Niagara areas.

The national weather agency said temperatures are expected to reach highs near or above 31 C.

680 NEWS meteorologist Jill Taylor said the high in the GTA on Tuesday will be 31 C but it will feel like 36 C with the humidity. As of 4 a.m., the temperature in Toronto hit 22 C.

The extreme heat is expected to continue into Wednesday and Thursday with a high near 33 C and 32 C expected on each respective day. Showers and thunderstorms are also in the forecast on both days.

“It’s not the first time that we’ve had a heat wave, if you will, three days of 32 C or more for three or more days. We had that June 18-20 at Toronto Pearson,” Taylor said.

The nighttime is not expected to provide much relief, with overnight lows of about 21 C expected.

People are being advised to keep out of the heat and to drink plenty of liquids.

Environment Canada issues a heat warning when “very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.”

The health risks associated with the heat are the greatest for seniors, children, people with breathing difficulties and heart conditions, the homeless, those who work and exercise in the heat, and people without access to an air conditioned space.
