PORTLAND, Ore. (KOIN) — A wildfire near Larch Mountain in Clark County that began late Sunday afternoon has now grown to 70 acres, the Washington State Department of Natural Resources tweeted.
No evacuations were expected overnight. Crews will begin to attack the fire by air once daylight begins Monday morning.
The fire is growing in grass and brush, officials said.
KOIN 6 News meteorologist Joseph Dames said the relative humidity will jump Sunday night as the temperatures drop. The general area of the Nakia Creek Fire will have a relative humidity pushing above 50% Sunday night (~60% on Saturday night). The greater the relative humidity the better for conditions. This allows for the transport of moisture to the fuels.
There is a fairly tame wind, but it will pick up Monday out of the northwest, especially by afternoon. There may be some wind around 15 mph at that time.
This is a developing story. KOIN 6 News will have more information as soon as possible.
Editor’s Note: A previous version of this story stated that fire officials did not believe the fire would grow beyond 70 acres. KOIN has since removed this statement.
