Environment Canada is confirming a weak tornado that hit Fort St. John last month. The tornado was generated by a severe thunderstorm Aug.

Tornados are a rare occurrence in BC and this tornado is the first one to be recorded in Fort St. John and surrounding area.

The animals are thought to have contracted the disease from exposure to dormant anthrax spores in the soil of a feeding site on a farm. This is the first documented case of anthrax in livestock in B.C

"I've worked forecast in this area for 33 years. It's very rare. I don't remember any community in B.C. having that much damage from a tornado in my career or in the Peace," said meteorologist Doug Lundquist.
