Heat Warning in effect for:

City of Thunder Bay

Extreme Heat arriving in Northwestern Ontario.

The dome of intense heat that has been in place over western Canada will move into northwestern Ontario today. Daytime highs will climb into the low- to mid-thirties. Overnight lows will be in the upper teens, providing little relief from the heat. Humidex values near 40 are expected on the weekend.

This extreme heat will last through the weekend and possibly into Monday for some areas.

Hot and humid air can also bring deteriorating air quality and can cause 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.

Check on older family, friends and neighbours. Make sure they are cool and drinking water

Never leave people or pets inside a parked vehicle.

Watch for the symptoms of heat illness: dizziness/fainting; nausea/vomiting; rapid breathing and heartbeat; extreme thirst; decreased urination with unusually dark urine.

Outdoor workers should take regularly scheduled breaks in a cool place.
