It's a deluge

The last time it rained this much in L.A. so early in the wet season was 1966—and that's before today's big Pacific storm arrives. There has already been 15.86 inches at the official measuring spot in Los Angeles. That's more than in an entire normal year. Forecasters say there could be five more inches dropped in L.A. this weekend and 15-20 inches in the mountains. Some of that will come down as snow, of course. "The entire state of California is pretty much under the gun for the next three or four days," said Duane Dykema with the National Weather Service in Monterey.

Out in Arizona, rivers are flowing for the first time in seven years.
