The BC Wildfire Service says smoke and haze visible in Kamloops is likely due to wildfires in Washington and Montana.
A smoke forecast from Firesmoke Canada predicts the smoke will leave the area by 6 p.m. Friday evening.
Montana's largest fire is the 1,000-hectare Magpie Rock Fire burning northwest of Missoula.
In Washington, the 700-hectare Anglin Fire is burning just across the border, about 50 kilometres south of Osoyoos.
