Warm weather has finally arrived in the Greater Toronto Area but accompanying it will be the city’s first heat event of the year.

Environment Canada issued a yellow heat warning for Toronto, Vaughan, Richmond Hill, Markham, Mississauga and Brampton, Ont., beginning Monday afternoon and ending Tuesday night.

Daytime highs will reach 30 C, which will feel like nearly 36 C, according to the the weather agency. Overnight lows will sit between 18 and 20 C.

Environment Canada meteorologist Kristina Kretchman says the sudden shift to hot weather may feel “dramatic” because of recent below-normal temperatures, but a hot spell at this time of year isn’t particularly unusual.

Kretchman says a warm air mass from the U.S. is moving up into Ontario, bringing extra heat and moisture.

In its warning, Environment Canada recommends watching for signs of heat exhaustion and heat stroke, including headaches, nausea, dizziness, confusion and intense fatigue.

The weather agency is reminding residents to remain hydrated, close blinds, open windows, turn on air conditioners and limit direct exposure to the sun and heat.
