Dust and smoke issues in the Great Basin Unified Air Pollution Control District

King Fire smoke turns and settles in

Posted by admin on September 19, 2014

Here is a view from our webcam on Mazourka Peak.  Overnight, the wind directions changed from southerly to northerly, causing the smoke from the King Fire in El Dorado County http://inciweb.nwcg.gov/incident/4108 to drift down into the Great Basin valleys.  The fire grew over 5,000 acres since yesterday and is expected to grow 10,000 more acres by tomorrow.  The winds will be shifting again, so it is uncertain whether there will be an increase is smoke to our area over the weekend.  Below that is a chart of the PM2.5 for monitors in Lee Vining, Devil’s Postpile and Bishop Paiute Tribe.  PM10 monitors in Mammoth Lakes and Bishop have been added.  The PM2.5 at these sites would be slightly less, but they still provide a reasonable estimate.  The communities have dropped back down into the Moderate or even Good range.  (REFRESH THIS PAGE throughout the day today for updates on the chart).  Cautionary and health effect statements for the color-coded categories are available at http://www.gbuapcd.org/pm10.htm.  Newly available is a health guide for schools from the Oregon DEQ.  It uses the same color codes for wildfire smoke (see below).
