Environment Canada has issued a thunderstorm warning for much of B.C.'s Interior, with the potential storm expected to bring strong winds and heavy rain to the region.

The federal forecaster released a special weather statement for the Okanagan, Similkameen, Shuswap, Columbias, Nicola Valley and the Kootenays.

"A vigorous cold front will cross the province on Wednesday bringing with it very strong winds aloft and an unstable airmass that is ripe for the development of strong wind gusts, heavy showers, and potentially thunderstorms," Environment Canada's statement reads.

The potential storm is forecast to hit the region on Wednesday, Sept. 25. Areas east of Golden and Creston towards the Alberta border should expect it on Wednesday night, Environment Canada said.

Boaters and watercraft users are advised of sudden strong gusts over lakes during this time, with motorists warned of potential strong crosswinds over high elevation highway passes.

Wednesday's storm could also produce heavy rainfall totals, localized flooding or water pooling on roads, the federal department added.

"Damage to buildings, such as to roof shingles and windows, may occur," the statement reads.

"High winds may result in power outages and fallen tree branches. Watch for possible washouts near rivers, creeks and culverts."
