In California, at least 3,000 people have been forced to evacuate the fast-moving Oak Fire near Yosemite National Park. As of this morning, the fire had burned nearly 17,000 acres and was just 10% contained. Smoke from the massive blaze triggered air quality alerts in the San Francisco Bay Area and other parts of the region.

In the Pacific Northwest, forecasters are warning of a new heat wave that could push temperatures in some areas above 110 degrees Fahrenheit. This follows record heat a year ago blamed for the deaths of 800 people across Oregon, Washington state and British Columbia.
