Pollen Alert
-Pollen Index: 8.6 Pollen Level: medium-high Predominant Pollen: Grass, Oak and Sorrel/Dock. The quantity of pollen grains in the air for Monday will be falling in the moderate range. This change results in part from falling temperatures and heavy rains in the morning which tend to wash pollen out of the air. Relief is in sight.
