Environment Canada has issued a heat warning for Winnipeg and much of southern Manitoba, with daytime highs expected to reach the low to mid-30s and overnight lows staying at or above 16°C.
The warning is in effect from Sunday through Tuesday.
Health officials are urging residents to take precautions as extreme heat can pose serious health risks, especially for young children, older adults, and people with pre-existing health conditions.
How to stay safe:
Environment Canada recommends staying hydrated by drinking water frequently—even before you feel thirsty.
The national forecaster suggests that if your home is not air-conditioned, try to spend time in cooler public places like libraries, malls, or community centres. If you’re outdoors, limit your exposure to the sun, wear light-coloured clothing, and plan activities during the cooler parts of the day.
People are reminded never to leave children or pets in parked vehicles, as interior temperatures can rise quickly to dangerous levels.
Know the signs of heat illness:
Watch for symptoms such as headache, nausea, dizziness, intense fatigue, dark urine, or fainting. These may be signs of heat exhaustion. More serious symptoms—like confusion, red and hot skin, or a loss of consciousness—could indicate heat stroke, which is a medical emergency. Call 911 if heat stroke is suspected and try to cool the person down while waiting for help.
Environment Canada says checking on vulnerable friends, family, and neighbours—especially those living alone—is crucial during periods of extreme heat.
