Bald Mountain Fire Update 9/19/18

Bald Mountain Wildfire
News – 9/19/2018

September 19, 2018 8 a.m.

Special Note: Great Basin Team 1 is hosting a Community Meeting, tonight, September 19, 2018 at 7:00 PM at Maple Hills HS in Mapleton, UT. Fire officials will be there to provide an update on each fire. The Rocky Mountain Type 1 Incident Management Team (IMT) is managing the Bald Mountain Fire and Great Basin Team 1 is managing the Pole Creek Fire. Both teams are cooperating when informing the public and sharing resources. Bald Mountain Logistics is supporting Pole Creek Division Z resources by feeding them and providing a camp nearer their work assignments. This keeps cost down and eliminates drive time reducing risks.

Weather: Another Red Flag Warning in effect Wednesday from 12:00 PM to 10:00 PM for winds 10-15 mph gusting to 20 mph with 25-35 mph gusts on ridges, low relative humidity of 10 % and high temperatures will reach 79°. The Haines Index, which measures the stability and dryness of air over a fire, is 6 (6 is the highest). This indicates a high potential for an existing fire to become large or exhibit erratic fire behavior. Winds will shift from southwest to west late afternoon and to northwest after 7:00 PM. Thursday should bring temperatures 10° lower and winds switching to the WNW.

Current Situation: With today’s Red Flag Warning, crews will continue efforts to secure the fireline. Much of the conifer fuel has burned and the fire has reached oak brush and other slower burning fuels. Some resources have been identified as Initial Attack to respond to any new starts in the area if needed.Smoke that was observed yesterday afternoon was the result of crews successfully implementing ground firing suppression actions on the south side of the fire in Division AA.

On the north side in Division J, contingency dozer lines were completed and aerial resources dropped water along the perimeter. Firing operations along this contingency line would only be used in order to protect these communities from an advancing fire. Today, crews will be constructing direct fireline in some accessible areas. Structure protection is in place; pumps, hose lays and sprinklers are tested regularly. A Mobile Retardant Plant and a Heliwell have been set up in Division J to improve efficiency and response times for aircraft and other resources.

Yesterday on Division AA, on the south end of the fire, crews successfully completed firing suppression actions along Nebo Loop Road to the southeast. This firing will continue today to connect with Pole Creek Fire’s Div. Z.

The fire has made no movement in Division A, on the west side of the fire, near Bald Mountain. Dozer work was completed and firefighters are monitoring contingency lines. Any excess resources will be shifted to other areas of the fire.

Firefighters in Division D, on the northwest corner, will continue construction of the contingency line around Santaquin subdivision. The dozer line from Payson Canyon west to the fire edge will be pretreated with retardant before crews use firing suppression tactics to remove a pocket of fuel between the dozer line and the fire. Residents should expect to see increased fire activity in this area. Hotshot crews will be going direct (building fire line directly along the fire edge) where safe. They will be spiked out for several days to have better access to the remote areas.

The night shift continues to monitor the fire and evacuated communities that have been provided structure protection. They are also monitoring and holding the day operations firing suppression actions. Last night they caught a 20’ x 20’ spot fire in Division AA.

Closures and Public Safety: The public is reminded to expect heavy fire traffic in Payson where the Bald Mountain Incident Command Post is located. Evacuations and pre-evacuations remain in place for several areas in the fire vicinity. A list of current evacuations is available at
