The B.C. Wildfire Management Branch says there was no significant growth in the fire Saturday morning and the blaze is now about 12.8 square kilometres in size.
A spokeswoman said about 6.7 millimetres of rain fell on the fire Friday, but warned winds and warmer temperatures could quickly change the situation.
High winds have been carrying heavy smoke throughout southern B.C. The fire is visible from Merritt, Kamloops and Vernon.
One home has been destroyed while 10 others remain under an evacuation order issued by the Lytton First Nation.
About 88 firefighters, seven helicopters and three pieces of heavy equipment have been brought in to battle the blaze.
