Pioneer Fire spreads north across Highway 21 near Lowman, Idaho

(UPDATED at 11 a.m. MDT August 6, 2016)

The Pioneer Fire at Lowman, Idaho, 32 air miles northeast of Boise, Idaho, continued to spread up the steep slopes after it crossed highway 17 Friday afternoon pushed by thunderstorm-generated winds gusting up to 35 mph. Spot fires initially occurred over the roadway west of the burnout firefighters were conducting near Lowman to protect the community. By 2 a.m. aerial mapping showed the fire had spread about 1.2 miles north of the highway and consumed an additional 1,200 acres.

On Friday the fire grew by about 6,700 acres, to 58,136 acres.

The video below of firefighters working along Highway 21 was posted by the incident management team on August 5.

The incident management team’s plans for Saturday, in part:

Crews will look for opportunities to bring dozer line north from Burns Ridge down to the river west of the fire in an effort to create a new containment line. North of the river the fire is established in steep slopes with light grassy fuels. Aircraft this morning will survey the fire west and north of Lowman looking for suitable places to build containment lines. The possibility of another thunderstorm today or tomorrow brings potential for stronger wind gusts, which could create more extreme fire behavior.

A strong south wind added to the complexity of the burnout being carried out since Thursday by firefighters in an effort to stop the Pioneer Fire from impacting the community of Lowman, Idaho and crossing Highway 21. Sustained winds at 20 mph with gusts of 28 to 40 mph pushed the blaze across the highway Friday, significantly increasing the workload now laid out before the incident management team.

Evacuations have been ordered by the Boise County Sheriff’s Office for some areas near the Payette River, and Highway 17 is closed. The fire is 32 air miles northeast of Boise, Idaho.

The 52,000-acre fire is being fought by 1,489 personnel, 43 hand crews, 52 engines, and 10 helicopters. Five structures have been destroyed.

NOAA experiments with forecasts for wildfire smoke

Wildfire smoke forecast
Wildfire smoke forecast for 6 p.m. MDT August 4, 2016

The National Oceanic and Atmospheric Administration is experimenting with a system that produces forecasts for the distribution of smoke from wildfires.

The examples of their products created at 6 a.m. MDT August 4 for near-surface smoke are included here — predicting conditions for 6 p.m. MDT August 4 (above) and 6 p.m. August 5 (below). Click the images to see larger versions.

Developers are collecting feedback from users to improve the model before it is considered for transfer into operations.

The HRRR-Smoke air quality modeling system simulates the emissions and transport of smoke from wildfires detected by the VIIRS/JPSS satellite fire product in high spatial resolution (3km) over the CONUS domain. Currently the model is run every 6 hours (00, 06, 12 and 18 UTC) to produce smoke forecasts for next 36 hours. The forecast products of near-surface and vertically integrated smoke concentrations are visualized on a GSD web-site in real time: http://rapidrefresh.noaa.gov/HRRRsmoke/

The spread of the Whit Fire west of Cody, WY slows

(UPDATED at 11:25 a.m. MDT August 5, 2016)

The Whit Fire 13 miles west of Cody, Wyoming was much less active Thursday than the day before. According to the aerial mapping during the last two nights it grew on the southwest and northeast sides by a total of several hundred acres, but the incident management team is still calling it 9,647 acres. The discrepancy could be related to issues with the imagery Wednesday night.

One home and seven outbuildings have been destroyed in the fire.

On Thursday two water-scooping air tankers, CL-415’s, were delighting tourists that were on US Highway 16 driving past the Buffalo Bill Reservoir on the way to Yellowstone National Park. The aircraft were skimming along the water surface loading about 1,600 gallons into their tanks and then flying to the fire, assisting firefighters by dropping water to slow the spread. The reservoir is only six miles from the fire, which enabled quick turnarounds.

Air tanker 263, a CL-415, scoops water from the Buffalo Bill Reservoir at 8:01 p.m. MDT on August 4, 2016 while working the Whit Fire. 

At times the vehicles stopped on or near the roadway created a safety hazard. Kristie Salzmann, a spokesperson for the fire, said law enforcement is now actively discouraging that practice. There are other locations that can be used safely, including various locations in the state park, and the boat launch which is closed since no boaters are allowed on the lake while the scoopers are working. The same aircraft are expected to be assigned to the fire on Friday.
