Gov. Tina Kotek has declared a state of emergency over the threat caused by wildfires burning tens of thousands of acres throughout Oregon.

Eight large wildfires are now burning across Oregon, with the largest topping 100,000 acres, according to the Northwest Interagency Coordination Center.

Out-of-state firefighters join Oregon's battle against surging wildfires, with reinforcements from Washington state aiding in the efforts.

Wildfires in eastern Oregon grew dramatically over the weekend and the danger of new wildfires had increased for the southern half of the state.
