Pollen Forecast for Nine Mile Falls, Washington

Based on past pollen counts and expected weather conditions, pollen levels for Thursday will be falling and will remain in the extremely low range. This decrease is due to falling temperatures and heavy rains in the afternoon which tend to wash pollen out of the air.

Concentration of pollen grains in the air for Friday will be rising in the moderate range. This is likely to be caused in part by strong winds and decreasing humidity. This heavy increase in pollen concentration could very well cause problems for those who are allergic to airborne pollens.
