ENTIAT, Wash. – Several hundred firefighters worked Friday to contain a fire that has burned grass and brush across nearly 30 square miles in Central Washington.

The blaze threatened more than 200 homes in Chelan County near Entiat, roughly midway between Seattle and Spokane.

The fire was partially contained by Friday afternoon.

Worried that hot, dry conditions would increase fire dangers, state officials extended an outdoor burn ban to include all 13 million acres of lands that the state protects.

A burn ban, which has already been in effect in Eastern Washington, now includes Western Washington. The ban is in effect through Sept. 30.
