LEAVENWORTH, Wash. (AP) — Calm weather is helping firefighters working on a small wildfire that is threatening dozens of homes in central Washington.

Fire information officer Alan Hoffmeister says the fire is burning on about 300 acres just east of Leavenworth.

Hoffmeister said about 100 homes remain under evacuation orders, but so far no structures have been lost.

The fire began Saturday afternoon near the town of Peshastin.

Hoffmeister says fire crews were aided Sunday by retardant planes and other aircraft dropping buckets of water on the flames. Authorities estimated that the fire was about 25 percent contained, but Hoffmeister said that estimate would likely change as more crews returned from the field to assist with mapping efforts.

Officials are investigating the cause of the fire.
