Okanogan County Sheriff Frank Rogers says it is too early to say how many homes have been burned by a series of wildfires in the county of 5,300 square miles. A series of wildfires in north-central Washington that left three firefighters dead grew by more than 100 square miles, but officials hope easing winds forecast for Saturday will allow them to gain the upper hand. Thousands of people remained under evacuation orders as strong winds drove flames across parched ground. Resources were so strained that Saturday, fire officials planned to provide basic fire training to about 200 volunteers who have machinery like backhoes and bulldozers so they can use them to help dig fire lines. The overall situation was too chaotic to even track how many homes had burned — though officials hoped to make progress on that front Saturday.
