The 2000 Pine Lake tornado was a deadly tornado that struck areas near Pine Lake in central Alberta,on Friday,July 14,2000,destroying a campground and a trailer park. Twelve people were killed,making it the first deadly tornado in Canada since 1987,when an F4 tornado killed 27 people in Edmonton,Alberta and injured 300+.[2]
The F3 tornado,which struck the Green Acres Campground at Pine Lake in central Alberta,killed 12 people and critically injured more than 100 others. The tornado formed out of a severe thunderstorm which formed on the eastern slopes of the Canadian Rockies and moved rapidly eastward,encountering a narrow band of low-level moisture that caused it to develop into a supercell thunderstorm. It touched down about 5km (3.1mi) west of the campground and was on the ground for approximately 20km (12mi).
Damage occurred in a swath 800 to 1,500 metres (0.50 to 0.93mi) wide. The heaviest damage occurred in a 500 metres (0.31mi) central corridor. Damage assessment suggests that winds within the central corridor reached 300 kilometres per hour (190mph). In addition,Weather Watchers reported hail as large as baseballs.
An average of 16 tornadoes occur in Alberta every year,and an average of 41 tornadoes occur each year in the Prairie Provinces. The highest death toll due to a single tornado in Alberta occurred on July 31,1987,colloquially referred to as Black Friday. Canada ranks second in the world for tornado occurrences after the United States.
