The Hawk Fire ignited on Peavine Peak in the Humboldt-Toiyabe National Forest, just northwest of Reno in Washoe County, Nevada, on 22 August 2026, with crews responding shortly before 11:25 am local time.
Nevada Governor Joe Lombardo declared a state of emergency for Washoe County the same day, directing all state agencies to work through the Nevada Emergency Operations Center and mobilising the Nevada National Guard.
Officials confirmed the fire was human-caused, though the exact ignition source remained under investigation.
The fire grew to 15,051 acres and destroyed 32 homes; some 42,000 residents were placed under mandatory evacuation orders at the peak, with another 45,000 in warning zones.
NV Energy carried out emergency de-energisation affecting up to about 60,000 customers, and Reno-Stead Airport was closed to general aviation while remaining open to firefighting and military aircraft.
Crews respond to the Hawk Fire on Peavine Peak shortly before 11:25 am; NV Energy begins emergency power shutoffs the same day.
Governor Joe Lombardo declares a state of emergency for Washoe County and directs state agencies to coordinate through the Nevada Emergency Operations Center.
The fire crosses the multi-lane U.S. Route 395 corridor; evacuation zones expand towards the edge of the University of Nevada, Reno.
Damage assessment confirms 32 homes destroyed; the burned area reaches 15,051 acres and containment is put at 27 per cent.
Fire officials report forward progress stopped, with crews working hot spots along the perimeter; mandatory evacuations reduced to about 23,000 residents.
The wildland-urban interface is the zone where houses and other built structures meet or intermingle with undeveloped vegetation. Fires here are far costlier than fires deep inside a forest, because a single wind-driven ember landing on a roof can start a structure fire kilometres ahead of the flame front - a process called ember spotting. WUI fires also force choices that pure wildland fires do not: mass evacuation, closure of highways used as escape routes, and the deliberate switching off of electricity supply so that power lines do not become a second ignition source. The Hawk Fire is a textbook case: it started on national forest land, jumped a multi-lane highway, and destroyed 32 homes on the suburban fringe of a city.
Simple Analogy: It is the difference between a fire in an empty field and a fire in the field behind a housing colony - the fuel is the same, but everything about the response changes once there are roofs downwind.
Peavine Peak rises immediately northwest of Reno in Washoe County, in the western corner of Nevada where the state meets California. The Humboldt-Toiyabe National Forest, which covers the peak, is the largest national forest in the contiguous United States. The fire spread across the U.S. Route 395 corridor and towards communities on Reno's northern fringe, with spread reported across the state line into rural tracts of northeastern California.
