The first significant heat event of the season continues to grip the region with dangerously hot conditions expected to last through early to mid-week, according to Environment Canada.
Daytime highs ranging from 31 to 36 C, with humidex values soaring between 40 and 45, are forecast for the coming days. Overnight lows are expected to remain uncomfortably warm, between 21 and 25 C, offering little relief from the heat.
Residents are urged to take precautions as extreme heat can pose serious health risks. Vulnerable groups, including older adults, those living alone, young children, and people with pre-existing health conditions, are particularly at risk.
Environment Canada advises checking in regularly on at-risk individuals and watching for symptoms of heat-related illness, such as headache, nausea, dizziness, dark urine, and fatigue.
Heat stroke is a medical emergency. Signs include red, hot skin, confusion, and loss of consciousness. Anyone exhibiting these symptoms should receive immediate medical attention.
The public is encouraged to plan outdoor activities during cooler parts of the day and to wear light, loose-fitting clothing. Vehicles should never be left unattended with people or pets inside.
