Hot, humid weather in store for Toronto with city under heat warning
CBC
Very hot and humid weather is coming to Toronto Tuesday and is expected to hang around until Thursday, Environment Canada says.
The federal weather agency has issued a heat warning for much of southern Ontario, forecasting daytime temperatures into the low 30s with humidex values soaring into the 40s. Night time temperatures will likely hover in the low 20s.
"So there will be very little relief from the heat overnight," says Katrina Eyk, a senior meteorologist at Environment Canada.
Heat warnings are posted when conditions are expected to pose a risk of heat illnesses, such as heat stroke and heat exhaustion.
The hot conditions may lead to the deterioration of air quality, Environment Canada says, which means the Air Quality Health Index could reach the "high risk" category at various points.
Residents are urged to drink plenty of water before they feel thirsty and stay in a cool place if possible. If you need to be outside, be sure to take regularly scheduled breaks in a cool area.
A cold front is expected to roll into the GTA on Thursday night, bringing relief from the heat by Friday morning, Eyk says.
As the mercury rises, the city said it would like to let residents know that it has officially opened its outdoor pools and 90 supervised wading pools.
The summer schedule for the city's outdoor pools and wading pools started Friday.
Outdoor pools will be open daily until Sunday, Sept. 3, at 4 p.m., except for 10 that will continue to be open until Monday, Sept. 4, at 5 p.m. Most of the city's outdoor pools are open daily from noon to about 8 p.m.
The city said people heading out to swim should check hours for specific pools here.
The city's more than 140 splash and spray pads will be open until Sunday, Sept. 17. Splash pads are open daily from 9 a.m. to 9 p.m. and are activated by a push button.
The city said lifeguards are supervising 10 city beaches seven days a week from 10:30 a.m. to 7:30 p.m. Beach-goers are reminded to swim in designated areas only.
