High winds around Vancouver on Monday morning have downed trees, knocked out power to thousands of residents and blown at least one large sailboat onto the rocks.

The windstorm knocked out power to 3,200 residents in Vancouver's Kitsilano, about 3,200 more customers on the North Shore and about 1,600 customers in Burnaby, Coquitlam and Port Moody.

A large cedar tree fell into a building near the intersection of Sixth Avenue and Alma Street in Vancouver, knocking the balcony off one of the apartments and nearly hitting a worker nearby.

There were also reports of trees hitting cars in the West End of Vancouver, and another hitting a bus shelter on the Mount Seymour Parkway in North Vancouver.

A 10-metre sailboat was badly damaged after its anchor line snapped and it was blown onto the rocks off Kitsilano Point.

Three other vessels were reported dragging their anchors, including a second near Kitsilano Point, a large fishing vessel near Heather Marina in False Creek, and another boat in West Bay in West Vancouver.

The windstorm reportedly knocked power lines onto the Barnet Highway, forcing officials to close the route to traffic.

An Environment Canada marine forecast included a gale warning for the area, warning the winds could blow up to 75 km/h overnight Monday before subsiding on Tuesday.
