The Hawk Fire burning northwest of Reno, Nevada, triggered the evacuations of over 90,000 people on Sunday, according to fire crews working the incident.

The wildfire, which ignited on Saturday morning and has since been determined to be human-caused, has burned over 15,000 acres as of Sunday evening. Nevada Gov. Joe Lombardo declared a State of Emergency soon after the fire started on Saturday as the fire spread rapidly.

“This is an active and rapidly evolving situation, and I urge everyone in the affected areas to remain vigilant and follow the direction of local officials,” Lombardo said in a press release regarding the emergency declaration. “The state is fully engaged, and we are working alongside local authorities and first responders to deploy every available resource to protect lives, safeguard communities, and keep Nevadans out of harm’s way.” 

Numerous communities are in GO NOW evacuation zones across the region, with local officials urging community members to check the Perimeter Map website for the latest evacuation updates. Officials have also closed numerous roads in the area, including highways and local streets. Winds up to 20 mph increased fire activity and drove fire movement Sunday afternoon into the evening, crews said.

Firefighters remained fully engaged on Sunday, working to extinguish hotspots and keep the fire south of U.S. 395, according to crews at the scene. Communities north of 396 are sandwiched between pending evacuations from the Hawk Fire to the south and the Bug & Stallion Fires to the north, which have burned over 93,000 acres and are 97% contained as of Sunday night.

The Washoe County School District canceled all school classes, except for Gerlach K-12 school, on Monday due to the ongoing fire. The district had just restarted classes for the new school year on Aug. 10.

“We understand that so many people in our WCSD family—students, families, and staff —are impacted,” the district said in a press release. “Over the next few days, we will continue to update our entire district family with information as it becomes available. We are grateful to our firefighters and first responders as they continue to battle this fire, and we thank our district personnel who are assisting with this effort.”
