Pollen Forecast for North Cascades Natl Park, Washington

The pollen levels for Sunday will be falling into the very low range. This forecast of lower pollen concentration is based on rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.

The amount of pollen in the air for Monday will be greater than today's levels but will still remain in the low range. This increase is due to seasonally normal weather conditions which are favorable for the production and dispersal of pollen.
