Environment Canada has upgraded its heat warning for Goderich, Bluewater, and southern Huron County from a yellow warning to an orange heat warning as dangerously hot conditions continue to build across the region.
Forecasters say the long-lasting heat event is expected to continue through Friday and could extend into the weekend. The hottest weather is expected from Tuesday through Thursday, when daytime highs could reach between 34 and 37 degrees Celsius in some areas. Overnight temperatures will remain between 21 and 25 degrees, offering little relief from the heat.
Environment Canada is also warning that the hot, humid weather could lead to poorer air quality, with the Air Quality Health Index possibly reaching the high-risk category.
Residents are encouraged to drink plenty of water, stay in air-conditioned or shaded areas whenever possible, and limit outdoor activities to the cooler parts of the day. People are also being asked to check on older adults, those living alone, and others who may be more vulnerable to heat-related illnesses.
Health officials say signs of heat exhaustion include headache, dizziness, nausea, intense fatigue, and thirst. Anyone showing signs of heat stroke, such as confusion, hot red skin, or loss of consciousness, should receive immediate medical attention by calling 9-1-1.
Environment Canada also reminds residents never to leave children or pets inside a parked vehicle, even for a short period of time.
The orange heat warning remains in effect for Exeter, Goderich, Bluewater, and southern Huron County, and residents are encouraged to continue monitoring forecasts and weather alerts as conditions develop.
