    Why would a 200-year event be expected soon?

      It could be that there is a correlation with solar maximum cycles. In 1862, the west coast of North America was subjected to the largest recorded so called ARK storms, for nearly a month straight. Coincidentally, 1859 was the year of the Carrington event–a repeat of either event will be difficult to cope with…

      Welcome to the new normal.

    Sadly, since these atmospheric rivers originate around Hawaii, they keep temperatures up meaning this is coming down mostly as rain even in Tahoe.

    In California we’ve used the term “Pineapple Express” to refer to this phenomenon for a lot longer than since 1998: a whole series of storms with lots of rainfall over a period of weeks. We rely on most of that water winding up as snow in the Sierra Nevada, where it melts at a nice steady rate so we have plenty of water in the dry season (which is bone dry: virtually no rain at all from mid-May to mid-October). If that winter precipitation winds up as mostly rain instead of mostly snow, Sacramento may be in serious trouble in wet winters.

      And dry summers.

      In SF we don’t just rely on snowpack for water — we rely on it for power as well.

      Agreed, it seems like we’ve been watching these on satellite for years.  Usually they move around and don’t flood one spot, but every once in a while they stay for a few days or weeks and disaster happens.

      Native Americans in the area do seem to have a lot of flood stories, I’ve noticed.

    It looks like a fist punching San Francisco in the face.

    MIMIC-TPW has a similar Pacific map (derived total precipitable water) that animates the last 3 days, each hour:

    My one major worry for Southern California: With weather patterns being grossly changed by Global Warming, if a hurricane from south of San Diego were to hit the city, it would be catastrophic!  Everything is focused for earthquake-proofing,  not flood/high wind proofing.  And the outlying suburbs would be pretty much wiped out.  -*(

    We’ve had 1.7 inches of rain in the last year.  If the drought holds for another three weeks, that’ll be 3.25 inches in two years.
