A tornado that hit the Grand Lake area last weekend produced winds of up to 175 km/h, Environment Canada has determined.
The tornado, which touched down near Jemseg on Saturday at about 7:30 p.m. and tracked in an easterly direction, has been classified as an EF-1 on the Enhanced Fujita Scale, the agency said in a statement.
The EF Scale goes from zero, indicating the weakest, with winds of between 90 km/h and 130 km/h, to five, being the strongest, with winds of 315 km/h or more.
EF-1 tornadoes account for about 25 per cent of all tornadoes and produce winds between 135 km/h and 175 km/h, said Gilbert Bouchard, of weather information services.
The tornado was classified based on the characteristics of the damage observed by the storm survey team that visited the site on Monday, he said.
The storm left a path of destruction about 15 kilometres long.
No major injuries were reported, but numerous trees were uprooted and at least three barns in the Whites Cove area were destroyed, scattering debris up to 350 metres away, said Bouchard.
Damage was also documented in the Cambridge Narrows area, he said, with at least three more structures damaged or destroyed, including a large barn. Debris from that barn was picked up and carried over 300 metres.
Power and communication outages were also reported.
Several amateur videos documented the funnel cloud.
Environment Canada had issued a tornado warning for the area earlier on Saturday.
