Due to prescribed burn activity in Yoho National Park, Alberta Health Services is issuing a precautionary fire smoke advisory for the communities East of the burn site, including Cochrane and Calgary, and surrounding areas.

Prescribed burns ensure smoke is managed more effectively than wildfires; however, smoke conditions in surrounding communities can vary depending on current weather conditions and prevailing winds.

Individuals may experience irritation of eyes, throat and possibly shortness of breath. Anyone experiencing symptoms can also call Health Link Alberta 24 hours a day, seven days a week, toll-free at 1-866-408-LINK (5465), to speak to a registered nurse.

This advisory will remain in effect for the duration of the prescribed burn, September 12 through September 14, 2011.
