Heat warning continues for GTA as scorching weather persists

The Greater Toronto Area remains under a heat warning for a second consecutive day, with hot and humid conditions expected to persist Thursday, says Environment Canada.

Daytime temperatures are forecast to reach 31 C, with humidex values making it feel 39. The federal weather agency said that the sunny weather has also brought UV index levels to 8, which is considered very high on Environment Canada's scale for the sun's UV rays strength.

During the day, there is a 60 per cent chance of showers and a risk of thunderstorms. Meanwhile, at night, temperatures are expected to go down to 21 C.

"A cooler airmass may arrive by tonight," Environment Canada said in a statement.

The city also offers various cooling stations, including community centers, indoor and outdoor pools, splash pads, wading pools, libraries, civic centers, malls, YMCAs and seniors centers.

Environment Canada warns that extreme heat can pose health risks, particularly for vulnerable groups such as older adults, young children, pregnant individuals, and those with underlying health conditions.

"Extreme heat can affect everyone's health," the agency said. "Drink plenty of water regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration."

The City of Toronto has extended the hours of some outdoor pools until 11:45 p.m. Those locations include Alex Duff, Giovanni Caboto, McGregor, Monarch, North Toronto, Sunnyside Gus Ryder and Smithfield.
