Powerful winds to wallop B.C.'s South Coast in aftermath of Vancouver tornado

Meteorologists issued heavy wind warnings for the Lower Mainland and other parts of B.C.'s coast on Sunday, one day after a rare waterspout was spotted over the oceannear Vancouver International Airport, bringing fierce winds to the University of British Columbia campus.

The windstoppledtrees, blockedroads and disruptedtransit on Saturday evening, sparking cleanup efforts and a brief tornado alert from Environment and Climate ChangeCanada.

The alert lasted only 24 minutes before the funnel cloud vanished, but the incident came amid a very windy weekend in the region, with worse conditions on the way.

"We issued a tornado watch as quickly as we could," meteorologist Armel Castellan told All Points West host Robyn Burns.

"This is the kind of eventthat happens so quickly that no forecaster out there would have had a tornado watch ahead of this event. For unheralded, unprecedented, historic events likethis in November, you are reactive to an event."

"I think we got lucky in the sense that nobody did get hurt.No fatalities."

Winds are forecast to reach at least 80 km/h starting Monday in Metro Vancouverand are expected to reach110 km/hon other parts of the B.C. coast.

According to Environment Canada, Metro Vancouver, Howe Sound and inland Vancouver Island can expectstrong southeast winds of 50 km/h, gusting to 70km/h Monday night and into Tuesday.

Those southeastern winds will be followed by southwest winds of 40 km/h gusting to 60 km/h, the weather service says.

'It's scary'

Laura De Pascalewas heading home from the UBC Fencing Clubwith a friend on Saturday when they both sawlightning.

"Then it started pouring hail," she recalled."There was just a bunch ofswirling branches andleaves.

"And suddenly, I don't think I fully realized at the time, I didn't even notice the tree that fell behind my car."

She said the strong winds caused a trolley line to break and fall right outside her car door.

"Once you have power lines starting to come downon your car, it's scary," she said.

De Pascale and her friendwere able to head home without injury but it's not an event she will soon forget.

"I still feel a bit of disbeliefandit's hard not to think about what could have gone wrong."

No injuries have been reported from Saturday's weather event.Several people recorded videos of the waterspout, a tornado that forms above water, and posted them to social media.

Bus routes affected by downed trolley lines

TransLinksaid trolley repair likely won't beginuntil Monday morning, asarborists aren't expected to finish the clean-up of fallen trees and debris untillate Sunday evening.

That means regular bus service may not commence until Tuesday.

Routes 004 and 014 will continue to use West 16Avenue to reachthe campus, while the 99 bus will use Chancellor Boulevard, said TransLink spokesperson Tina Lovgreen.

Winds picked up across Metro Vancouver over the weekend, with other parts of the region seeing downed trees and branches unrelated to the tornado.

Meteorologists continue to analyze the phenomenon that descended over UBC on Saturday around 5 p.m. PT, but it's not the first time B.C.'s coast has seena funnel cloud.

"Waterspouts can occur over the Strait of Georgia or other coastal waters throughout the year it's not actually all that uncommon. However, this one was quite a large one," Bobby Sekhon, a federal meteorologist with Environment and Climate Change Canada, told CBC News.

"Seeing it close to land is a little bit more rare, especially moving through land certainly close to populated centres."

Sekhon said it was caused by a "broad trough" of low pressure, with cold air atop warm air, creating an "unstable environment" combined with "spin" in the atmosphere on Saturday.

"Those ingredients kind of came together and formed this waterspout," he said.

And although the phenomenon is not unprecedented in this region, this one was rare for its size and how close it got to a major city.

He said winds in funnel clouds can hit 80 to 100 km/hor more, but this one did not register on local weather stations.

Sekhon said the chances of another waterspout or tornado are very slight.

"Any time you see a funnel or even worse, a tornado, over water or over land it can be life-threatening there can be strong wind speeds," Sekhon said. "You want to stay away from anything that might be flying around."
