Selkirk is under an orange-level heat warning Monday as a dangerous heat wave continues to grip the region, with Environment Canada forecasting humidex values feeling like 44 to 47 in direct sun. The warning, in effect for the R.M. of St. Andrews including Selkirk, Lockport, and Ponemah, means residents face a serious risk of heat-related illness if they do not take precautions.
Daytime highs on Monday will reach 33°C, but with humidity it will feel like 44 to 47 degrees in direct sun. The UV index is very high at 9. The multi-day event has already shattered temperature records across the province, with Winnipeg hitting 35.3°C and a humidex of 48 on Sunday. Overnight lows are only dipping to about 18°C, offering little relief.
Manitoba Health, Seniors and Long-Term Care issued a heat advisory on Friday, July 10, urging everyone to take precautions. Heat illness can affect anyone, but older adults, infants, people with chronic conditions, outdoor workers, and those without housing are at the highest risk. Officials recommend drinking water before feeling thirsty, closing blinds during the day, and checking on vulnerable neighbours and family members several times a day.
Those without air conditioning are encouraged to seek relief at cool public spaces such as community centres and libraries, as recommended by Environment Canada. The province says two consecutive days of daytime highs at or above 32°C, overnight lows of 16°C or higher, and humidex values of 38 trigger a heat warning. A U.S. heat dome pushing north is trapping southern Manitoba in this multi-day event. Residents can call Health Links-Info Santé at 204-788-8200 or 1-888-315-9257 with health questions.
