'Mini-twisters' spotted over Lake Okanagan in Kelowna (VIDEO)

A series of dancing miniature “tornadoes” were spotted over Lake Okanagan in Kelowna last week when the arctic blast of subzero temperatures hit much of British Columbia.

The steam fog phenomenon is called “arctic sea smoke” and occurs when very cold air moves over the warm air over the surface of warmer water. A funnel of steam can appear when light wind blows over the surface of the water.

Time lapse video captured by the Okanagan Wedding Network on November 30 shows the phenomenon occurring over Lake Okanagan when temperatures dipped to -18°C in the Okanagan Valley.
