MONTREAL -- After a week of off-and-on smog warnings, the Greater Montreal Area is about to get hit with some heat and humidity to start the week.
Environment and Climate Change Canada (ECCC) issued a heat warning Sunday for the Montreal and Laval islands in addition to areas on the South Shore.
"A warm and humid air mass will enter Quebec early this week and persist into Friday," the ECCC said in its warning.
The heat will rise particularly on Monday and Tuesday where temperatures are expected to exceed 30 degrees Celsius with humidex values hitting 40.
Nights won't be any cooler, according to ECCC, with lows nearing 20 degrees.
During a heat warning, residents are advised to watch for effects of heat illness including cramps, fainting, heat exhaustion and swelling.
"Drink plenty of water even before you feel thirsty and stay in a cool place," ECCC said. "Never leave people or pets inside a parked vehicle."
