Wildfires prompt evacuations along the West Coast and hazy conditions as far as the East Coast

Extreme heat and dry conditions are fueling raging wildfires in the western US, charring more than a million acres, requiring evacuations and creating smoky conditions visible from space.

The fires have caused power outages, destroyed structures and prompted the deployment of the Oregon National Guard. As extreme drought still grips most of the West and the fires have become so intense they've created their own weather systems, the threat of more fires remains.
