Air stagnation advisory in effect through the weekend

Stagnant air is in the weekend forecast due to high pressure over the West Coast.

Light winds, a strong inversion layer and limited air mixing prompted the National Weather Service to issue an air stagnation advisory through 1 p.m. Sunday.

“Diminished air quality is likely to cause health issues for people with respiratory problems if precautions are not taken,” a Weather Service bulletin said.

The coverage area includes sections of Jackson, Josephine, Klamath and Douglas counties.

Restrictions on wood stove burning will likely be in effect during the advisory due to increased levels of particulate matter in the air. Residents are asked to call 541-776-9000 to hear daily wood stove advisory updates.

Late Friday morning, air quality was “moderate” at monitoring stations in Medford, Shady Cove, Grants Pass and Cave Junction, according to the Oregon Department of Environmental Quality. Levels remained “good” in the Applegate and Ashland.

A weak front is forecast to push into the area and break up the loitering air mass by Sunday night.

“We’re not expecting significant precipitation or anything like that, but it should be enough to stir up the atmosphere and mix out some of the pollutants,” said Weather Service meteorologist Marc Spilde, adding that less than 0.1 inch of rain is expected along the Oregon Coast. “We’re not going to have hardly anything here in the Rogue Valley.”

Another front is expected to push into the region Sunday night into Monday, increasing the chance for rain, but not by much.

As of Friday, Medford had recorded 3.26 inches of rain since Oct. 1 — the start of the water year — which is 0.37 inch above normal for that date, Weather Service officials said. By comparison, Medford had seen only 0.67 inch at this point in the last water year.
