A wildfire that has spread into Yosemite National Park is now threatening the power grid that supplies San Francisco, prompting Gov. Jerry Brown to declare an emergency for the city.
The 200-square-mile Rim Fire also threatens thousands of homes and has forced the evacuations of hundreds.
Bob Hensley, reporting for NPR, says that in issuing the state of emergency for the city of San Francisco and San Francisco County late Friday, Brown indicated the wildfire has damaged the electrical infrastructure that provides power to the Bay Area 150 miles to the west.
Updated at 12:35 a.m. Saturday: Emergency For San Francisco
Calif. Gov. Jerry Brown declared a state of emergency for San Francisco because of the wildfire's threat to public utilities there.
The fire is 150 miles from the city, but Brown said the fire jeopardizes San Francisco's power lines and stations in the fire area. The city has already had to shut down two of its three hydroelectric power stations, the AP reports.
Further damage could have an impact on San Francisco's power supply.
The 2013 wildfire season hit a milestone Tuesday: Preparedness Level 5, an officious way of saying resources are stretched thin and it could quickly get worse.
Preparedness Level 5 is the highest on the national wildfire preparedness scale, which the National Interagency Fire Center uses to chart wildfire activity, the deployment and availability of firefighters and equipment and the likelihood that more big fires are coming.
