(AP) — Fire officials say they're making progress on Washington's massive wildfires in central in eastern Washington, but warmer drier weather is expected to make things more challenging over the next few days. Two big fires burning on the Colville Indian Reservation are now more than 50 percent contained, but fire officials say there are still active areas within the interior of the North Star and Tunk Block fires, which together have burned nearly 575 square miles.
