Residents across Norfolk County are being urged to take precautions as the first major heat event of the season continues across the region.
Environment and Climate Change Canada has issued a yellow heat warning for Norfolk County, forecasting daytime highs near 30 degrees Celsius along with humidex values approaching 36. Officials say the hot and humid conditions are expected to continue through the day before easing tonight.
The agency notes that temperatures may be somewhat cooler near the Lake Erie shoreline, but inland areas are expected to experience more intense heat throughout the afternoon.
Public health officials are reminding residents that extreme heat can affect anyone, particularly older adults, young children, people living alone, and those with pre-existing health conditions. Residents are being encouraged to check in on vulnerable family members, friends, and neighbours multiple times throughout the day.
Officials are also warning people to watch for symptoms of heat exhaustion, including headaches, dizziness, nausea, intense fatigue, thirst, and dark urine. Anyone experiencing those symptoms is advised to stop physical activity, move to a cooler area, and drink water immediately.
Heat stroke remains a serious medical emergency. Symptoms can include confusion, red or hot skin, nausea, dizziness, and loss of consciousness. Residents are being told to call 9-1-1 immediately if someone shows signs of heat stroke while taking steps to cool the person down using shade, cool water, or ice packs.
Environment Canada recommends drinking water regularly before feeling thirsty, keeping blinds or curtains closed during the hottest parts of the day, and using fans or air conditioning where available. Residents without access to cooler indoor spaces are encouraged to visit public facilities such as libraries, community centres, or shaded parks.
Officials are also urging residents to avoid strenuous outdoor activities during peak afternoon temperatures and to wear lightweight, loose-fitting clothing and wide-brimmed hats when outside.
Drivers are also being reminded never to leave children or pets unattended inside parked vehicles, even for short periods of time, as temperatures inside vehicles can rise dangerously fast.
