Heat wave could push humidex to 45 in Manitoba, Saskatchewan

Much of Saskatchewan and Manitoba are bracing for a significant heat wave expected to begin Friday. Environment Canada forecasts temperatures will approach 30 C, with humidex values potentially reaching a scorching 45 by Sunday. Special weather statements have been issued for broad areas of both provinces, particularly south of the Trans-Canada Highway where humidity will be more pronounced. The intense heat is anticipated to persist well into next week, with daytime highs remaining in the high 20s to low 30s even as conditions gradually ease. Heat warnings are likely to be issued as the event draws nearer. Adding to the discomfort, wildfire smoke continues to impact air quality and visibility in parts of northeastern Manitoba and southern Saskatchewan. Residents, especially vulnerable groups like the elderly, young children, pregnant individuals, those with chronic health conditions, and outdoor workers, are urged to minimize outdoor exposure during periods of high heat and smoke. Environment Canada also recommends keeping windows and doors closed to stay cool.
