A heat warning is in effect for Greater Sudbury and vicinity, with hot temperatures expected to last through Thursday.
Daytime high temperatures near 30 C today and in the low 30s on Wednesday and Thursday with overnight lows near 18 are expected, said the heat warning, issued by Environment Canada late Tuesday morning.
Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index to approach the high risk category.
Extreme heat affects everyone.
The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
Drink plenty of water even before you feel thirsty and stay in a cool place.
Never leave people or pets inside a parked vehicle.
Outdoor workers should take regularly scheduled breaks in a cool place.
