Pollen Alert
-Pollen Index: 11 Pollen Level: high Predominant Pollen: Maple, Ash and Alder. Based on past pollen counts and expected weather conditions, pollen levels for Monday will be falling but will remain in the very high range. Since the weather has a major influence on pollen dispersal, this decrease is due in part to falling temperatures, rising humidity, and expected precipitation in the morning and evening which tends to wash pollen out of the air.
