PORTLAND, Ore. (KOIN) — Amidst cooler temperatures and higher humidity levels, firefighters continued to make progress in their fight against the Nakia Creek Fire in Camas, Washington. But, evacuation levels remain unchanged from Monday.

It’s estimated that over 2,500 people are still under evacuation.

Officials say crews have been able to establish a fire line and the size of the fire has been updated to 1,796 acres. There are three small spot fires burning to the north and northwest of the main fire body, but they are all within the established fire lines.

Monday night, firefighters bolstered the lines, began clean-up, and kept structural task forces near homes in a nearby neighborhood, officials said.

Firefighters will continue building lines Tuesday and improving weather conditions should allow for the use of aircraft, including water scooper planes, to fight the fire — nearly 400 firefighters are attempting to diminish the flames.

KOIN 6 News also found out more about a vehicle that the Clark County Fire Marshal is trying to track down. The sheriff’s office says a person shooting video on Oct. 9 captured two men and two women shooting off pyrotechnics around 3:30 p.m.

Although the fire is only 5% contained, Matt Howard, Incident Commander with the Oregon Dept. of Forestry, expects that percentage to grow quickly.

“We’ll be here until the job is done, until we turn it over to the DNR towards the end of the week, going into the weekend. We are really looking forward to the rain that’s coming in, but that’s not detracting us from the work that needs to be done until then,” he said.
