The wildfire was sparked on Sunday by lightning. It's now grown to four hectares, fuelled by strong winds and dry conditions, according to fire officials in the Central Okanagan Regional District
Dramatic images on social media show it burning down the western slope of Okanagan Lake above Westside Road.
The BC Wildfire Service says the fire is burning at Rank 4, which is described as a vigorous surface fire.
The service says in a release that an evacuation order has been recommended to the Central Okanagan Regional District for approximately 30 properties in the Shelter Cove area.
The district has confirmed to CBC News that it is trying to move people out from residences and properties along Westside Road near Shelter Cove between La Casa and Lake Okanagan Resort.
Those impacted are asked to report to the Emergency Support Services reception centre at the Westbank Lions Community Hall, 2466 Main St. in West Kelowna.
More than 20 firefighters are currently battling the fire without the help of helicopter or air tanker support as it's too dangerous to fly to the fire in darkness.
