UPDATE: The advisory has now been lifted 

Tuesday afternoon, Environment Canada issued a special weather advisory warning that funnel clouds could form in the Cochrane area and other locations in southern Alberta. 

Funnel clouds are generated by weak rotation under rapidly growing clouds or weak thunderstorms.

The funnel clouds could transform into a landspout tornado which does not usually cause significant damage but can still be dangerous. Strong winds can cause damage to roofs, blow over trees, and throw debris.

Environment Canada urges everyone to treat any funnel cloud sighting seriously. Should a funnel cloud develop nearby, prepare to take shelter. These funnel clouds usually appear with little or no warning.

This weather advisory is in effect for: 

  • Rocky View Co. near Cochrane
  • Mountain View Co. near Carstairs and Stirlingville
  • Mountain View Co. near Cremona and Water Valley
  • Mountain View Co. near Olds and Didsbury
  • Mountain View Co. near Sundre
  • Rocky View Co. near Airdrie and Crossfield
  • Rocky View Co. near Bottrel and Madden
