Air Quality Hurt By Gusty Winds
Gusty winds blowing dust off Eastern Washington fields Thursday afternoon made for hazy skies in North Idaho. Air quality - while not entering potentially dangerous levels - dropped through the afternoon, according to Idaho Department of Environmental Quality monitors.
Staff members at DEQ blamed winds gusting from the southwest at up to 25 mph.
“I imagine the winds are just picking up and moving soils from any exposed fields,” said Dan Redline, DEQ’s air quality manager in Coeur d’Alene. “We just happen to be downwind.”
Dust particles can trigger asthma or other health problems in people with respiratory problems.
State gauges measured one-hour levels in Coeur d’Alene at 70 micrograms per cubic meter, far below the 150 trigger level for air quality warnings, but more than twice the usual levels this time of year. Forecasted rain showers were expected to hold down particulate levels today.
Last September, loose soils blowing off Palouse and Columbia Basin wheat fields whipped up a shower of dust from Spokane to Coeur d’Alene. “Hopefully it won’t be as bad as last year,” Redline said.
