It's some 150 miles away, but a massive wildfire burning in the Sierra foothills in and around Yosemite National Park has triggered a state of emergency in San Francisco, reports the Chronicle. The Rim Fire threatens transmission lines that carry power to the city, along with the reservoir that serves as its water supply. The fire, now 200 square miles and only 5% contained, has crossed into Yosemite on the park's remote western border, though the Yosemite Valley area most popular with tourists remains open and might emerge unscathed, reports AP.
"Right now there are no closures, and no visitor services are being affected in the park," says a spokesperson. "We just have to take one day at a time." More than 2,700 local and federal firefighters were on the scene last night, but strong winds were making things difficult. The Los Angeles Times reports that mountain communities that depend on late summer tourism were being hit hard.
