Weather: Southern slopes of the Bighorn Fire received approximately 0.1 to 0.25 inches of rain from Saturday evening thunderstorms. Sunday will be the hottest day of the year so far, with temperatures in the valley reaching 113 degrees. Minimum humidity levels will range from around 11 to 16% across the lower elevations to 20 to 30% over the higher elevations. The Excessive Heat Warning issued for Southeast Arizona remains in place through Monday evening.

Yesterday’s Activity: Crews completed chipping operations at the Mt. Lemmon SkyCenter and Mt. Bigelow, and felled hazard trees in Spencer Campground. During the late afternoon, outflow winds from nearby thunderstorms aligned with fuels and pushed the fire along the north side of the West Fork Trail #24. This increased fire activity produced a smoke column above Sabino Canyon that was visible from Tucson. Evening thunderstorms and associated rain moved through the area and tempered that fire growth.

Today’s Activity: Firefighters will be identifying and assessing hazard trees that may require removal due to the high winds received over the fire area last night. Chipping, backhaul, and suppression rehabilitation will continue in the Summerhaven area, as well as other portions of the fire.
