Alberta’s chief medical officer is warning people with respiratory problems to remain indoors as a pall of acrid smoke from British Columbia forest fires hangs over the province.

Prevailing winds are blowing the smoke into much of Alberta and other weather conditions are keeping it close to the ground, turning normally blue skies a dusky grey.

 

“I strongly advise people with asthma, bronchitis or emphysema to remain indoors, keep their windows closed and take any preventative measures their physicians have previously recommended,” Dr. Andre Corriveau said.

 

Organizers for the Canadian Derby Edmonton Marathon say the smoky conditions will not affect the running of the event this weekend.
