The Regional District of Central Okanagan placed approximately 50 homes on evacuation alert early Monday morning, after flames jumped a fireguard and the blaze spread from 3.3 to 26.6 hectares overnight due to strong downhill winds.
Those houses remain on evacuation alert.
Westside Road has been reopened to single lane alternating traffic. It was closed Monday while the B.C. Fire Service did a controlled burn to create another fire barrier.
The fire was started by a lightning strike Friday night, and fire officials thought it was completely contained until late Sunday.
Fire information officer Kayla Pepper said as of late Monday night, the fire was 75 per cent contained.
