View Soldier Basin Fire in a larger map
Location: Sierra Vista Ranger District, Coronado National Forest, 5 miles east of the Nogales Airport
Estimated Size: approximately 6,000 acres
Cause: human caused, under investigation
Resources Assigned: approximately 205 personnel including 3 helicopters, 11 engines, 2 Type 1 hotshot crews, 4 Type 2 hand crews, 7 water tenders, and miscellaneous overhead
Fire Behavior: moderate with some short uphill runs
Terrain: steep, rocky
Fuel: grass and brush (mesquite and oak)
Structures Threatened: none
Wednesday's Weather Forecast: Variable southwest winds 10-15 mph. Temperatures will be in the 80s to lower 90s.
Relative humidity will range from 4 to 8%.
Objectives: Keep the fire south and west of Flux Canyon, west of Forest Road 49, north of the Solder Basin drainage, and east of the Coronado National Forest boundary.
Summary: Wednesday fire personnel plan to continue burnout operations along the north and north east flanks to tie the main body of the fire in with prepared lines.
Area residents should expect to see continued fire growth and smoke as firefighters continue aerial ignitions over the next 4-5 days. These operations will be conducted both with aerial ignition and fire fighters using drip torches on the ground. There will be increased smoke along the north flank due to burnout operations, particularly late in the afternoon. Fire activity will be highly visible, especially at night.
There is no threat to structures, as all fire activity is within the prepared fireline.
Travel Advisory: Beginning on the afternoon of Wednesday, May 22, motorists using FR 4698 and FR 49 into Soldier Basin should be prepared for possible delays due to burnout operations and fire personnel and vehicles working along the road. Fire personnel will escort vehicles through the area with pilot vehicles. It is recommended that motorists use alternate roads or avoid the area altogether until these operations are complete.
Smoke: Residents east of the fire will likely experience increased smoke impacts over the next few days. Smoke is likely to settle into canyons and valleys and other low-lying areas when air temperatures cool at night. Warmer temperatures and light winds usually help with smoke dispersal during the day. Breathing smoke is not healthy for anyone, but some people are at greater risk, including people with heart or lung disease, children, and the elderly. If it looks smoky, you may want to limit or eliminate exercise or other outdoor activities. For additional resources, please visit http://wildlandfire.az.gov/links.asp#Smoke.
