Pullman - An unfortunate overlap in tree and grass pollination combined with brisk winds is posing challenges for people whether they're allergic or not. The proof is before their eyes -- and in them.
Grasses in the Inland Northwest are pollinating hard on the heels of a tree pollination season delayed by a cool and damp spring, according to arborist Tim Kohlhauff of WSU's extension program in Spokane. Add windiness to the mix and "it's kind of like a dust storm, but with a yellow tint to it," he said.
Yesterday's pollen readings from the National Allergy Bureau's regional monitoring station in Coeur d' Alene show high concentrations from three tree species and all types of grasses.
Pollen levels have been surging into the high range intermittently since May 23, first from trees that pollinated roughly two weeks later than normal, and more recently from grasses that flourished in spring's cool, wet weather, said Kohlhauff.
