Heat warning in GTA expected to end Wednesday night: Environment Canada
Temperatures could feel like 36 C on Wednesday, according to Environment Canada
A heat warning covering much of the Greater Toronto Area is expected to end on Wednesday night, Environment Canada says.
The warning is in effect for the following areas: Toronto, Vaughan, Richmond Hill, Markham, Mississauga, Brampton, Oakville, Halton Hills and Milton.
But relief is expected sooner in other parts of southern Ontario, such as Durham and northern York region, which should see temperatures ease Tuesday night, the weather agency says.
In much of the Greater Toronto Area, daytime highs on Tuesday reached 31 to 32 C, feeling more like 41 C.
On Wednesday, the city is expected to see a high of 31 C, but will feel like 36 C with humidity.
Watch for symptoms of heat stroke
Environment Canada is advising people to limit exposure to sun and heat by planning activities during the coolest parts of the day, as well as wearing a wide-brimmed hat and lightweight, light-coloured, loose fitting clothing.
People are advised to watch for symptoms of heat stroke, which is a medical emergency, in themselves and others. Symptoms can include red and hot skin, dizziness, nausea, confusion and change in consciousness.
"While you wait for medical attention, try to cool the person by moving them to a cool place, removing extra clothing, applying cold water or ice packs around the body," Environment Canada said in Tuesday's warning.
The weather agency also advised people to drink water often, even before feeling thirsty, and close blinds and open windows if the outside is cooler than inside.
"If your living space is hot, move to a cool public space such as a cooling centre, community centre, library or shaded park," the heat warning says.
People are also advised to check in regularly on those at greater risk of heat illness, including the elderly and those living alone.
Signs of heat exhaustion may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. If you experience these symptoms, Environment Canada advises stopping your activity and drinking water.
