Predominant Pollen: Alder, Cedar/Juniper and Birch.

Outlook

The pollen levels for Saturday will be greater than today's levels in the moderate range. This results in part from higher temperatures and the lower dewpoint.

Today

The pollen levels for Friday will be falling in the moderate range. This relief in pollen levels is caused in part by falling temperatures, rising relative humidity and weaker winds.

Allergy Fact

Although plants with showy flowers tend to be less allergenic, some still cause allergy if their pollen becomes airborne. An example is the tree called catalpa, which has large, distinct, and numeous white flowers, and is a source of allergy for some people.
