Pollen Alert
-Pollen Index: 9.9 Pollen Level: high Predominant Pollen: Mulberry, Sycamore and Ash. Pollen concentrations for Monday will be falling but will remain in the high range. This lowering of pollen concentrations is a result of rising humidity, weakening winds and expected precipitation in the morning and evening which tends to wash pollen out of the air.
