A heat warning is in effect for Selkirk, Manitoba, and nearby communities as hot and humid weather settles over the region for the rest of the week. Environment Canada issued the warning early Tuesday morning, with daytime humidex values expected to hit 38 and feel even hotter on Wednesday.
The warning covers the Rural Municipality of St. Andrews, including Selkirk, Lockport, and Ponemah. Overnight lows will only drop to the upper teens or low 20s, offering little relief from the heat.
Wednesday is forecast to be the most uncomfortable day, with a high of 33 degrees Celsius and a humidex reading of 41. Environment Canada considers any humidex over 40 as extremely high. Manitoba Health may issue its own heat advisory when the humidex reaches 40 or above, urging people to adjust their activities to avoid heat-related illness.
Health officials are reminding residents to drink plenty of water, stay in air-conditioned spaces when possible, and check on neighbours who may be more at risk. Older adults, infants, pregnant people, and those with chronic health conditions are especially vulnerable. People who work or exercise outdoors, as well as those without stable housing, are also at higher risk.
Heat stroke is a medical emergency. Signs include red, hot skin, dizziness, nausea, confusion, or a change in consciousness. Anyone seeing these symptoms should call 911 immediately. For general heat-health questions, Manitobans can call Health Links – Info Sante at 204-788-8200 or toll-free at 1-888-315-9257.
The hot spell is part of a broader heat event across southern and central Manitoba, with some areas under an orange-level warning where conditions are expected to be even more intense.
