Due to stagnant weather conditions and rising air pollution, the Puget Sound Clean Air Agency issued a Stage 1 burn ban for Snohomish County effective at 1 p.m. Friday, Jan. 1.

This ban is in effect until further notice.

Clear, cold, and calm weather conditions should continue into Sunday, the agency said. With calm winds allowing air pollution to remain, continued cold temps, and ongoing wood burning, unhealthy air pollution levels are likely to linger for a few days.

During a Stage 1 burn ban, use of fireplaces and uncertified wood stoves and inserts is prohibited. Pellet stoves, EPA-certified wood stoves and inserts are allowed. Outdoor burning is also prohibited.

The Washington State Department of Health recommends that people who are sensitive to air pollution limit their time spent outdoors, especially when exercising. Air pollution can trigger asthma attacks and cause difficulty breathing. Air pollution is especially harmful to people with lung and heart problems, people with diabetes, children, and older adults (over age 65).
