CALGARY - Residents across southern Alberta will spend Wednesday picking up the debris after wicked weather whipped across the province.

High winds downed power lines and monsoon-like rains flooded streets.

At least two tornadoes were reported to have touched down near Taber, leaving more than half the town without power.

No injuries were reported when the funnel clouds touched down just after 8:30 p.m. in fields south and east of Taber, a town of 8,000 about 275 km southeast of Calgary.

"Damage-wise, lots of trees and portions of trees that are down and a good portion of the town has no power," Taber police Sgt. Steve Meggison said.

"Beyond that, there's high winds, lots of rain and lots of lightning."

Another tornado touched down 10 km north of Brooks about two hours later, Environment Canada reported.

No damage or injuries were reported.

That storm cell then headed north toward Calgary, arriving about 11 p.m. with high winds and heavy rains.

"We got hammered down around Haysboro and those areas earlier," Calgary Fire Department battalion chief Al Magwood said.

"There's some underpasses downtown that usually flood out and we've had some history at Heritage and Macleod, that one usually fills up pretty good.

"It all depends how much stuff is over the drains and how fast the rain is coming down."

The system formed over the Lethbridge area around dinner and began moving north at about 55 km/h, Environment Canada meteorologist Blair Morrow said.

"You'll notice it's been feeling quite warm and moist so we have a lot of energy," he said.

"Then we have a lot sheer, or strong winds, from different directions so we had all the prime ingredients for the development of severe storms."

Residents were in for a long night but were holding up, Taber Mayor Ray Bryant said.

"Right now we've had a lot of wind but it's just on the dark side and cloudy," he said.

"Our ambulances and fire units are prepared.

"We're ready in case and everyone is hopefully settled in."
