Coal Hollow Fire started Aug. 4 due to a lightning strike and increased rapidly in size by wind-driven runs. It is located in southeast Utah County near U.S. 6 and Dairy Fork.

Firelines were tested by strong winds on Friday night and Saturday afternoon, but have held. The recent increase in acreage has largely been due to planned firing operations. Firefighters are continuing to tie together sections of completed firelines, increasing the overall containment to 47% on Sunday.

Significant Events

Moderate, Uphill runs, Group Torching, Backing.

Fire behavior potential remains high due to hot, dry conditions and unstable atmospheric conditions combined with very high ERC's

Outlook

Planned Actions

Continue to secure northwest flank of the fire utilizing U.S. 6 as an anchor point. Utilize direct tactics along the northern perimeter, where appropriate, and complete indirect line and burnout as conditions allow. Secure indirect lines along the southern perimeter and complete burnouts as conditions allow.

Projected Incident Activity

12 hours: Calm conditions will return to the fire area, however the hot dry conditions will persist. Very unstable lower atmosphere will encourage spotting and column development that can accelerate fire growth.

24 hours: Stronger winds from the southwest will return to the area, however there is no precipitation expected.

48 hours: Hot and dry conditions will continue to further cure live fuels and further dry out surface fuels.

72 hours: Increased thunderstorm activity has the potential for outflow winds and lightning

Remarks

Number of structures threatened estimated based on county data. Number of civilians evacuated is a rough estimate based on imperfect structure data and a rough estimate of recreational public in the area.

Current Weather

Weather Concerns

High pressure building over the Great Basin kept winds terrain driven across the fire today. Smoke from surrounding fires created a haze over the area slowing warming through the day. The warmer, drier, and unstable air that is returning to the region has increased the Haines Index to a 5. Monday moisture starts to work its way back into the ridge increasing the potential for thunderstorms. The major concern with Monday is the big increase in ridge top winds from the southwest. Wind gusts up to 25 mph will be possible on Monday.
