The Northern Tornadoes Project (NTP) has concluded that the tornado which caused destruction in a rural area near Glencoe, Ont., last Thursday was stronger than first estimated.
The storm’s rating was upgraded from an initial EF-0 to a confirmed EF-1 over the weekend.
An EF-1 rating is the second-lowest on the Enhanced Fujita scale, indicating wind speeds between 135 and 175 km/h.
This updated assessment followed an area survey conducted by researchers.
“This supercell tornado had a path length nearly 10 km long and caused damage mainly to barns, trailers, and trees,” NTP researchers, based at Western University, wrote in a report on the tornado. “No injuries were reported.”

The tornado struck at 5:47 p. m. on June 25, according to the NTP. It occurred during a series of thunderstorms that produced high winds, heavy rain, and multiple tornado warnings across parts of southwestern Ontario that afternoon.
It traveled 9.6 kilometers with a maximum width of 250 meters and wind speeds reaching up to 145 km/h.

Researchers from the Northern Tornadoes Project at Western University looked into a tornado that touched down in Glencoe, just west of London, Ont., on Friday. So far this year, four tornadoes have been confirmed in this area.
The tornado west of Glencoe marks the fourth confirmed twister to hit the broader London region since early May, following earlier incidents near Lucan, through south London and near Melbourne.
