Heat Warnings Issued Across Southern Prairies as Prolonged Heat Event Takes Hold

A prolonged period of intense heat is expected to develop across much of the southern Prairies and continue well into next week, prompting heat warnings and special weather statements across parts of Saskatchewan and Manitoba.


Warmer air moving northward will bring daytime temperatures into the low to mid-30s across many southern regions, particularly near the Canada–United States border.


Combined with rising humidity, humidex values are forecast to exceed 45 in some areas, with the most oppressive conditions expected on Sunday.


In southern Saskatchewan, temperatures were expected to reach or exceed 32 C, leading to the issuance of heat warnings for most of the region. Orange-level heat warnings were issued for areas extending from Moose Jaw eastward to the Manitoba border, while yellow-level warnings remained in effect elsewhere.


Meanwhile, a Special Weather Statement remained in effect across Manitoba as hot and humid conditions continued to build. Forecast highs in the Red River Valley on Friday were expected to range between 28 C and 30 C, with humidex values in the low to mid-30s.


The heat event is expected to persist through much of next week, increasing the risk of heat-related illnesses. Residents are encouraged to stay hydrated, limit strenuous outdoor activities during the hottest parts of the day, and check on vulnerable individuals, including seniors, young children, and those with underlying health conditions.


The hottest conditions are expected across southern portions of the Prairie provinces, with little relief anticipated until later next week.

Forecast confidence:

High

 

Impact scale:

Moderate

Extreme heat can become dangerous quickly. Here are some important safety tips:


Stay Hydrated

  • Drink water regularly, even if you don’t feel thirsty

  • Avoid too much caffeine or sugary drinks

  • During heavy activity outdoors, take frequent water breaks

Stay Cool Indoors

  • Use air conditioning if possible

  • Close blinds or curtains during the hottest part of the day

  • Use fans, but remember that fans alone may not prevent heat illness in extreme temperatures

Avoid Peak Heat

The hottest part of the day is usually between 11 a.m. and 4 p.m.

  • Limit strenuous outdoor activities during this time

  • Schedule exercise or yard work early morning or evening

Dress for the Heat

  • Wear lightweight, loose-fitting, light-coloured clothing

  • Use a wide-brimmed hat and sunscreen outdoors


Never Leave People or Pets in Vehicles

Temperatures inside a parked car can rise dangerously fast — even with windows cracked open.


Watch for Heat Illness

Signs of heat exhaustion:

  • Heavy sweating

  • Dizziness

  • Weakness

  • Nausea

  • Headache

Move to a cool place and drink water.


Signs of heat stroke (medical emergency):

  • Confusion

  • Fainting

  • Very high body temperature

  • Hot, dry skin or stopped sweating

Call emergency services immediately if someone shows signs of heat stroke.


Check on Vulnerable People

Older adults, infants, young children, outdoor workers, and people with health conditions are at higher risk.


Protect Pets

  • Ensure pets always have fresh water and shade

  • Avoid walking dogs on hot pavement

  • Watch for overheating signs like excessive panting or lethargy
