SUNDRE, Alta. - An intense summer storm caused a tornado and dumped golf-ball sized hail on areas near Calgary this afternoon.

 

Environment Canada meteorologist Chris Wielki says the storm system passed just west of Sundre, producing a tornado that was spotted by a trained weather watcher and by a pilot in a hail-seeding aircraft.

 

He says there are no reports of damage from the tornado so far.

 

Wielki says there is still a weather warning for areas just west of Cochrane.

 

That system hasn't resulted in any reports of tornadoes, but Wielki says it has produced golf-ball-sized hail in the area.
