There are now 60 firefighters, four helicopters and four pieces of heavy equipment fighting the fire, which increased to 460 hectares from 430 overnight.
In spite of the increase, crews say they're making progress because of the additional resources.
Last night the crews appeared to be focusing their efforts on the southern flank of the fire, which is threatening the 70 lakeside homes on Westside Road that are on evacuation order.
Steep terrain and dry conditions continue to challenge firefighting efforts.
BC Hydro said 1,100 homes continue to be without power. However, it will provide 900 of them with six hours of power, on a rotating basis from a different circuit.
The firefighters might get some relief, as the weather forecast calls for rain in Kelowna over the weekend. But the hot, dry conditions are expected to return by Monday.
