ADVISORY: Smoke from the Swan Lake fire on the Kenai Peninsula is trapped below the low level clouds and is impacting the air quality for Southcentral Alaska. Expect smoke from the wildfire to spread throughout of northwest area of the Kenai Peninsula, specifically impacting air quality in the communities of Sterling, Soldotna, Kenai, and Nikiski. Air Quality will vary between GOOD and UNHEALTHY depending on wind flow and proximity to the fires. See the table below for more guidance on the Air Quality Categories and Cautionary Statements.
Be aware that areas immediately downwind of any fire will experience HAZARDOUS levels of smoke. Generally, worse conditions occur overnight and during the earlymorning hours, as the atmosphere cools and brings smoke to the surface. During the day,surface heating will mix smoke and carry it upwards, temporarily improving air quality.
SMOKE AND PUBLIC IMPACT: This is an area forecast, and as such is a general forecast for portions of Southwestern Interior Alaska. Smoke intensity will vary depending on precise location and local wind flow patterns. Smoke concentrations will be such that they could impact public health at times. It is advised that travelers check local weather as smoke conditions may vary considerably from one locality to the next. The most recent weather observations may be found on National Weather Service’s homepage at http://pafc.arh.noaa.gov/obs.php.
