Environment Canada has confirmed that a tornado touched down Monday night in a rural area east of Winnipeg.

The twister hit near Oakbank shortly before 9 p.m. CT.

Environment Canada said it will probably not send a damage team out Tuesday because only downed trees were reported as a result of the twister.

Area resident Judy Dunn said hail was coming down sideways, and the wind tore lots of branches from her willow trees, driving some of them into the ground.

"[The sky] darkened up as it usually does — we've had a lot of that weather this year," Dunn said. "The only difference is when that sky starts to turn kinda green, you know it's not a good thing,"

The weather agency also said storms through southern Manitoba brought hail the size of golf balls to areas around La Salle, Starbuck and Garson.

Hail larger than golf balls pelted several communities south of Winnipeg. (Collin and Tammy Shirtliff)A cleanup effort is also underway in Whiteshell Provincial Park, where a storm hit about 10:30 p.m. CT Monday.

Some cottagers at Caddy Lake, about 150 kilometres east of Winnipeg, along the border with Ontario, were still without power Tuesday afternoon.

An employee at a Green Bay resort in Caddy Lake told CBC News that high winds brought trees down onto cabins and loosened boats from their docks.

Laura Tanner said most boats have been recovered, although not without sustaining damage.

An estimate of the damage has not yet been determined.

Cottager Lauren Konrad said so much rain fell that a road at the resort was washed out for a time.

"There was so much lightning … we were running to try and get in the basement of someone's cottage, and a bunch of trees were coming down as we were running. I actually ended up going in to someone else's cottage because it was closer," she said.

Humidex warnings in place for much of the province on Monday were dropped at night as temperatures fell.
