Yesterday was the start of a heat wave in some parts of the GTA. The temperature reached 33 degrees celcius in Markham yesterday but fell just short of 32 degrees at Toronto’s Pearson International Airport.
Environment Canada criteria for a heat wave is three consecutive days of at least 32 celcius temperatures.
Today’s forecast is for more of the same as yesterday; mainly sunny and 33 celcius for the high. A little hotter than that, and Toronto could break a high temperature record of 34.4 degrees which stands from July 28th 1964.
An Environment Canada Heat Warning is in effect, advising you to watch for symptoms of heat illness including dizziness and fainting and to treat them by moving to a cool place and drinking liquids, preferably water. You’re also advised to frequently visit older neighbours and those who are chronically ill to make sure they are cool and hydrated. And never leave people or pets in a parked vehicle or in direct sunlight.
