Pollen Forecast for Great Smoky Mountains Natl Park, Tennessee

The pollen levels for Saturday will be falling and will remain in the extremely low range. The cause for the falling pollen levels is rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.

Pollen concentrations for Sunday will be at about the same level in the extremely low range. Because pollen is produced by growing and blooming plants, no such plants means no local pollen.
