Edmonton Alberta Tornado ( Mutiple Vortex )

July 31, 1987 Canada has had a handful of violent tornadoes. On the day of the Hermitage twister in 1985 (look for it in my uploads), the city of Barrie Ontario was devastated by an F4. This clip is of the Edmonton twister in its developing stages, captured on home video. This tornado was also F4, and killed 27 people. Check out the massive bowl-shaped wall cloud. The multiple vortices in this thing are wild; it rivals the Oshkosh tornado of April 21st, 1974 for the most dramatic example of a multi-vortex storm. Sorry, the quality of the footage isn't the best. Credit: ???
