NorCal preps for promised ARKstorm: 12 Inches?

CA has had no significant extreme weather since December 2010, when a series of atmospheric rivers took an unexpected tour fhrough Southern California.

Both the precipitation totals and the graphics for "ARKstorms" are jaw-dropping. In 2011, the USGS issued a massive report on an ARKstorm that left the entire Central Valley approximately six inches deep in water, forced the evacuation of Sacramento — including the government — for over a year, and would have destroyed the California economy, if the California in that era had a full-scale economy.

That was in 1862, when it poured buckets for twenty-eight days virtually without a stop. It could happen today; in fact, it happens every 180 years or so. Some suggest chances for these storms have improved as warming puts more water vapor in the atmosphere. Should that kind of "big one" return, the disaster experts say it would break up the California economy, send the US into a recession that could be major, and probably damage the world economy

This time the ARKstorm, as the Weather Service wonkily terms them, has Sacramento in its sights.  and residents are being told to prepare for twelve inches of rain and power outages

But rain is also predicted for SoCal, so I can't be too upset about it…
