Southwestern Public Health is urging residents to prepare for a stretch of dangerous heat as an Extreme Heat Warning takes effect across Elgin County, Oxford County and the City of St. Thomas.
Environment Canada is forecasting a multi-day heat event beginning Monday and lasting through at least Wednesday, with the possibility of extending into Thursday. Daytime temperatures could reach 35 degrees, while humidex values may climb to 42. Overnight temperatures are expected to remain around 23 degrees, offering little relief.
Southwestern Public Health issues an Extreme Heat Warning when temperatures are forecast to reach at least 31 degrees with overnight lows of 20 degrees or higher for two consecutive days, or when the humidex is expected to hit 40 or more for two days.
Health officials are reminding residents to take precautions, especially those most vulnerable to heat-related illness, including older adults, infants and young children, outdoor workers, and people experiencing homelessness.
Residents are encouraged to stay in air-conditioned buildings whenever possible, avoid prolonged sun exposure during the hottest part of the day between 11 a.m. and 4 p.m., drink plenty of water, take cool showers, wear sunscreen with an SPF of 30 or higher, and check regularly on family members, neighbours and friends who may be at greater risk. Children, seniors and pets should never be left unattended in parked vehicles.
Anyone experiencing signs of heat-related illness should seek immediate medical attention by calling 911 or visiting the nearest emergency department. Residents are also encouraged to monitor the latest forecast and locate public cooling centres if needed.
