California fire threatens San Francisco water and power
LOS ANGELES (AFP) - A raging California wildfire burning on the northern tip of the storied Yosemite National Park now threatens San Francisco's water and electricity supply, officials said Sunday.
The Rim Fire has charred through 54,220ha, growing nearly 3,400ha overnight, according to InciWeb, the online Incident Information System that monitors fires in the western United States.
The fire was just seven per cent contained, InciWeb said, adding that it "remained fairly active overnight in most all divisions," and exhibited "rapid rates of spread, torching and spotting" on its eastern edge.
More than 2,800 firefighters, supported by helicopters and air tankers, are struggling to contain the blaze, which started on Aug 17 from still unknown causes.
