Fire agencies are expected to continue prescribed burn operations this week in the Tahoe Basin.
The U.S. Forest Service says prescribed fires are used as a way to reduce fuels that could feed future wildfires.
Federal, state and local fire agencies have been conducting these burns since October near Tahoe City, Meyers, Stateline and Zephyr Cove.
The North Lake Tahoe Fire Protection District may continue prescribed fire operations on the west side of Incline Village this week.
Where and when to start a burn depends on weather, including conditions that allow the smoke to carry up and out of the Lake Tahoe Basin.
The Forest Service says smoke from prescribed fire operations is normal and may continue for several days.
Each prescribed fire operation follows a burn plan, which considers temperature, humidity, wind, moisture of the vegetation, and conditions for the dispersal of smoke.
