About pollen in Tri-Cities
Weed pollen is the main story in the Tri-Cities today, running at a moderate level. That is enough to cause noticeable symptoms for those who are sensitive, particularly with time spent outdoors in the afternoon, though it should stay manageable for most people going about their usual routines. Looking ahead, weed pollen is expected to hold steady at this same moderate level through the next several days, with no significant rise or fall in sight. This fits the pattern for mid-August, as late-summer weeds such as ragweed become the dominant pollen source in the region while tree varieties like alder and birch remain quiet until next spring. Anyone who reacts to weed pollen should expect similar conditions to continue into the week ahead.
