Bill Williams Mountain and Sitgreaves Fire

WILLIAMS – As of yesterday, the Bill Fire, located on the northeast side of Bill Williams Mountain is currently 3/10th acre in size. Crews hiked back to the fire today, improved the fireline perimeter and are now mopping up. The fire is 100% contained as of today. Smoke may still be visible as interior fuel and downed logs continue to burn.

The Mountain Fire, located on the southwest side of Sitgreaves Mountain, is 4 acres in size. Smoke is visible from Interstate 40, Highway 64, and the communities surrounding Sitgreaves. The Mountain fire is in mixed conifer with many dead, standing trees and steep slopes that pose a significant risk to firefighter safety. We are currently monitoring the fire and implementing a full suppression strategy. Firefighter and public safety is our highest priority.

Warm weather with 20% precipitation and the chance of isolated to scattered showers and thunderstorms are expected to continue across the area through Saturday, which will allow continued spread and production of smoke. A 70-90% chance of precipitation and monsoon moisture is expected to return Sunday and into next week bringing cooler temperatures and more rain, likely reducing fire spread and smoke.

Two New Fire Starts on the Williams Ranger District

WILLIAMS – This morning, crews are responding to two new fire starts on the Williams Ranger District.

A lightning storm passing through the area last night started a new fire on the northeast side of Bill Williams Mountain’s steep slope area. It was reported at approximately 5:45 a.m. this morning. The Bill fire is currently at 3/10th of an acre. Smoke is visible from town. Crews hiked up from the ski area early this morning and responded with a full suppression strategy. Six firefighters built line around the fire and are now mopping up.

Additionally, a new start was reported last night on the southwest side of Sitgreaves Mountain, above 8000 feet elevation. Two engines are responding this morning to assess this fire and are implementing a full suppression strategy.

Lower Sycamore Creek, Parsons Trail to close Saturday due to flash flooding risk

SEDONA – A portion of the Coconino National Forest surrounding Sycamore Creek will temporarily close at 6 a.m. Saturday due to an increased risk of flash flooding.

The closure area includes Parsons Trailhead, Parsons Trail north (including Parson’s Spring), and the confluence of Sycamore Creek and the Verde River.

The purpose of the temporary area closure is to protect the public from increased risk of flash flood events during the monsoon season due to the post-fire debris that has accumulated in Sycamore Creek due to the Rafael Fire.

The Rafael Fire burned through the Sycamore Creek drainage in June 2021, leaving large amounts of debris within lower Sycamore Creek. Monsoonal rains occurring locally or within the border watershed may cause flash flooding due to steep canyons located around the creek. Due to the span of the creek’s watershed, storms that can create flash floods in the Sycamore Creek area can occur miles away and may not be easily visible.

The Coconino NF will coordinate with the National Weather Service in determining when to lift this temporary closure. The closure will remain in place until monsoonal precipitation decreases enough that the area can be safely reopened.

The Coconino NF will continue monitoring the status of debris in the closure area and will determine when and whether to close the area again due to risk of flash flooding.
