Environment Canada has released more details on Tuesday's tornado that touched down. Spokesperson Geoff Coulson says the tornado tracked roughly 80-kilometres from Oxdrift, north of the Dryden Airport and northeast between Lac Seul and Sioux Lookout. Coulson says the tornado is being rated as a zero event, which is the weakest on the tornado ranking scale. Coulson notes the time it took for the tornado to blow through was unusually long, but notes the exact length isn't known at this time.
