With more 30-plus highs in the forecast, Environment Canada has issued another heat warning.

Daytime highs of over 30 degrees Celsius are forecasted for both today and tomorrow. Wednesday we'll dip slightly to a high of 26 degrees but bounce right back to 32 on Thursday.

Relief is on the way Friday, with the first of several days of rainfall, dipping the high to under 20. 

Heat warnings are issued when very high-temperature conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.

Alberta Health Services recommends taking these actions during the severe heat.

  • If planning on being outdoors:
    • Apply sunscreen of at least sun protection factor (SPF) 30, at least 20 minutes before heading outdoors. Be sure the SPF 30 screens out both UVA and UVB rays, and reapply frequently (as directed on product label).
    • Wear a wide-brimmed hat and sunglasses (with a UVA/UVB CSA-certified seal).
    • Wear light-coloured long-sleeved shirts and pants that cover skin.
    • Consider rescheduling outdoor activities to cooler hours of the day.
    • Drink plenty of water and other non-alcoholic, non-caffeinated beverages to stay hydrated.
  • Take frequent breaks from the heat, and spend time indoors. 
  • Do not leave any person or pet inside a closed vehicle, ever.

They advise people to be on guard for themselves and others for heat stroke. Symptoms include:

  • high body temperature
  • lack of sweat
  • disorientation
  • fainting
  • unconsciousness
