LEAVENWORTH, Wash. -

A wildfire raging in central Washington is threatening several homes and has prompted officials to order evacuations.

The State Fire Marshal's Office says in a statement late Saturday that the Chelan County blaze has burned about 400 acres and is growing.

KOMO-TV reports the fire began at 3:30 p.m. near the town of Peshastin. Chelan County Emergency Management officials tell the station that power outages are possible as the blaze may affect high-voltage wires.

The fire marshal's statement says the American Red Cross has set up a shelter at Icicle River Middle School in Leavenworth.

Officials are investigating the cause of the fire.
