For Grande Prairie and area: 


Extremely hot temperatures of 30 to 35 degrees Celsius combined with overnight lows of 14 degrees Celsius or greater are expected until at least mid week.

Daytime highs will gradually increase to near 35 degrees Celsius by Wednesday for many regions of Alberta. Overnight lows in the mid teens will not provide much relief from the heat.

For Dawson Creek/Fort St John:

Areas in the 100 Mile, Cariboo, Yellowhead, North Thompson, Fort Nelson and BC Peace River areas have a strong ridge of high pressure over the region and will continue to result in very high temperatures. 

These temperatures are expected to moderate starting Thursday.
