Air Quality Summary Report - Pioneer Fire For: Monday, September 5, 2016

Air Quality Summary Report - Pioneer Fire             For: Monday, September 5, 2016 

ARA: Mark Fitch (mark_fitch@nps.gov)                                ARA (T): Eric Dobbs (eric.dobbs@freshfromflorida.com)
FIRE, WEATHER AND SMOKE SYNOPSIS
Weather:  Slightly drier conditions will be seen this afternoon, diminishing the chance for showers and reducing cloud cover slightly.  A trough axis will transition across the region today, causing weak north-northwesterly winds early this morning to shift to a westerly direction by late morning and throughout the rest of the day.  Overall, wind speeds will be relatively weak near the surface and aloft with transport winds primarily out of the west this afternoon.  Up-canyon winds will be around 4 – 7 mph after 1:00pm while ridge winds will be a 7 - 10 mph with gusts to 15 mph over exposed ridges.  Inversion will break between 1pm and 2pm.
Fire Activity:  Yesterday, the fire grew 80 acres putting the current interpreted size to 181,145 acres.  Cloud cover, weak wind speeds, and moderate RH values will limit fire activity this afternoon.  The most active fire activity will be seen north of HWY 17 and HWY 21 in the Clear Creek, Deadwood, and Bear Valley drainages. Relative humidity (RH) values will be around 25 – 30 percent in lower valleys and 35 – 40 percent in high elevations.  Grass and shrub fuels will be active for uphill runs in valley locations.  Wind/slope alignment may result in moderate spread rates; however significant spread rates are not expected due to low-level moisture and weak winds.
Smoke Summary:  Smoke will concentrate in the low valleys this morning and mix down to the surface for much of the day.  The majority of areas will see clearing in the mid-to-late afternoon hours as daytime mixing peaks.  Smoke will begin to settle into the valleys in the mid-to-late morning hours with the biggest impacts for areas northeast, east, and directly south of the fire. Today, the most significant smoke impacts will be to Lowman, Stanley, and Garden Valley.
