KELOWNA, B.C. - Wildfire conditions were calmer across British Columbia on the weekend, but there is concern climbing temperatures and gusty winds could undo progress made over the last several days.

Environment Canada is calling for winds gusting to 40 kilometres per hour over the Kelowna area and lightning is also forecast for several parts of the province, including the Okanagan Valley.

The Wildfire Service says it conducted a successful controlled burn on Sunday, uniting two fires into one larger blaze between Peachland and Summerland, on the west side of Okanagan Lake.

That fire now covers just over 15-square kilometres.

While the blaze is still considered out of control, officials say the single perimeter offers a greater chance to build fire guards.

The Regional District of Okanagan-Similkameen rescinded several evacuation orders for properties north of Summerland and the wildfire service website says other evacuations could be lifted, but another 900 properties remain on alert until further notice.
