Fast-moving wildfires in eastern Washington state forced about 60,000 people to evacuate the Spokane area and destroyed at least 600 homes, businesses and other structures, authorities said Sunday. Three separate fires erupted in and around the city as strong winds and exceptionally dry conditions fueled rapid fire spread. The blazes were identified as the Old Trails Fire, the Fairview Fire and the Meadowview Fire. The fires razed entire neighborhoods, leaving many residents with little time to flee. The evacuation order covered a wide area, and emergency shelters were opened for displaced residents. Officials warned that the destruction could grow as crews continued to battle the flames. The cause of the fires was not immediately reported, but the combination of gusty winds and parched vegetation made conditions ripe for the infernos to expand quickly. No casualties were reported, though officials said assessments were ongoing. The fires added to a destructive wildfire season in the region, which has seen dry weather and extreme heat heighten the risk of blazes across the Northwest.
