Edmonton Journal has reported:

Environment Canada issued a yellow wind warning just after 1 p.m. Saturday for Edmonton, Sherwood Park and St. Albert, cautioning that gusts could reach 100 km/h. By early afternoon, windows were rattling downtown and the wind’s whistling was described as rock-concert loud. At 2 p.m., the agency recorded gusts of up to 98 km/h at Edmonton International Airport.

A line of thunderstorms and showers had developed west of Edmonton and was moving east along the Yellowhead corridor. Environment Canada said high winds could damage roofs, fences, branches and soft shelters, and advised securing patio furniture and other loose items in yards.

Driving conditions were expected to be difficult, particularly on open road stretches and for drivers of high-sided vehicles. At 2:11 p.m., Epcor reported 10 separate power outages in Edmonton. Glenora residents confirmed their power was out, while Epcor also showed outages in Westmount, Laurier, Crestwood, the Hamptons, Secord, Rosenthal, Ottewell, Terrace Heights and Boyle-McCauley.

A pro-separatist rally planned for 3 p.m. at the Legislature was pushed back to 4 p.m. as the windstorm continued. Organizers said “high winds have delayed setup.” Buses travelling to the event were also delayed by highway conditions.

The warning covered Edmonton and the neighbouring communities of Sherwood Park and St. Albert. The forecast gusts of up to 100 km/h were slightly higher than the 98 km/h maximum recorded at the airport by 2 p.m. The agency’s damage guidance included potential harm to roofs, fences, branches and soft shelters, while its travel caution singled out exposed stretches and high-sided vehicles.
