'Extended heat wave' as temperatures rise in Montreal

Montreal forecast: Heat extends through the week Montreal is looking at warn temperatures and some rain on the way. Here's your forecast.

A special weather statement has been issued for Montreal due to a "hot and humid air mass" that is "currently affecting the province of Quebec."

Environment and Climate Change Canada (ECCC) is warning of an "extended heat wave," with humidex values of 35 to 39 expected Monday afternoon through to Tuesday.

There won't be much reprieve during the nights, with lows of 18 degrees Celsius or higher.

The weather agency is predicting some rain on Wednesday, but the heat is expected to return on Thursday, with humidex values near 40.

"Heat and humidity may also persist through Saturday," ECCC notes. "The feeling of discomfort will be particularly acute in urban areas, where temperatures could reach a few degrees higher."

The Quebec Health Ministry is reminding people to protect themselves against the heat.

In addition, people are being reminded to never leave a child or a baby alone in a vehicle or poorly ventilated room, even for a few minutes.

"Check on and be ready to help your loved ones, especially those who are functionally dependent, disabled, mentally ill or living alone," ECCC states. "Remember that heat can also affect the health of pets."
