BC has joined AB in issuing alerts for the incoming hot spell, although shy of warning criteria as it’s in SWS form.

An extended stretch of hot weather is expected…

A ridge of high pressure will strengthen over BC through Sunday, leading to several days of above seasonal temperatures. Afternoon temperatures will rise a couple degrees each day this week. Daytime maximum temperatures will reach the mid to upper 30’s Thursday through the weekend. Overnight conditions will also remain quite warm.

The heat combined with the warm and dry weather from June will increase the fire danger rating across much of southern BC.

Please refer to the BC Wildfire Service for updated Fire Danger Ratings.

Heat related illnesses are more likely during prolonged periods of hot weather. Everyone is at risk of heat related illness. Those most vulnerable to high temperatures include young children, the elderly who are housebound in un-air-conditioned homes, those working or excersising in the heat, persons with chronic illnesses, heart and lung conditions, people living alone in un-air-conditioned homes and the homeless. If you are taking medication, particularly for mental illness, heart disease or Alzheimer’s disease, ask your doctor or pharmacist whether it increases your health risk in the heat and follow their instructions.

Seems some eastward shifting in the core of the heat but little suggestion of meaningful large-scale & lasting change at the moment.

This outlook certainly isn’t going to help the fire situation across the region.
