The Washington Department of Natural Resources said the Nakia Creek Fire was human-caused, but officials are continuing to investigate what sparked the fire, which grew to 250 acres Tuesday near Larch Mountain.
The fire — burning in the Larch Block of the Yacolt Burn State Forest — was 10 percent contained, and 97 firefighters were battling the blaze, according to the Department of Natural Resources.
About 220 homes along the Clark-Skamania county border were issued evacuation warnings, as of late Tuesday afternoon.
The vast majority of these notices were Level 1 — Be Ready. About 14 addresses fall under a Level 2 notice — Be Set. As of Tuesday afternoon, no residents were under a Level 3 notice — Go Now, according to Eric Frank, emergency management coordinator for Clark Emergency Services Agency.
“These notices are voluntary and precautionary. Those living in these areas should take steps to prepare to go and make plans on relocating any livestock that may be in the impacted area,” Frank said in a post on Nextdoor.
Officials determined the fire must have been caused by humans because of a lack of lightning in the area, said Trina Contreras, a spokeswoman with the Department of Natural Resources.
Firefighters worked on control lines along the flanks of the fire Tuesday, but officials said the potential for the fire to grow remains. It is burning in slash and previously harvested slopes, according to an update.
A high pressure system is expected to keep weather warm and dry throughout the week, the Department of Natural Resources said.
The steep, rocky terrain has been a challenge for firefighters, and crews continued to utilize air units Tuesday to fight the blaze.
The Clark County Sheriff’s Office reminded people to not fly drones in the area because the Federal Aviation Administration has issued a Temporary Flight Restriction, though private drones have been seen in the area, which slows aerial firefighting efforts.
