We get no rain all summer and then get "atmospheric rivers" worth. The
geometry of SF funnels a lot of water into the low spots. We had a
mudslide+rock just the other side of the canyon from our house, on
O'Shaughnessy Boulevard.

5" rain in one day is a record. 20" a year is common.

We have a single sewage+drainage system, which can be nasty.

Yeah- water is heavy, it will blow manhole covers off their seats. The mud slurry can be lethal, probably over 100 lbs/cu.ft., will knock you off your feet at ankle height, bury and drown you if it has any flow to it. That antiquated sewer runoff water system is doing more than you know. When water treatment is overwhelmed, it is let loose untreated into Bay or wherever it is they do it. That's just the obvious stuff. It will take a few weeks to make the news, but I'm sure there are more than few highly toxic retention ponds overflow and general area contamination.

I've done the Paris and San Francisco sewer tours. SF was more fun and
smelled a lot better.

There's actually a (stinky) cafe' in the underground Paris sewer
complex.

Well, Paris is thousands of years older than SF. That's a lot of water under the bridge.

Same here, Dec 31 was the warmest ever recorded,
at midnight I had like +15.1 C Celsius...
and it has been raining now intermittently for week.

What is your latitude longitude there? Where do your prevailing winds come from?

Sugar Bowl, the ski area at the Sierra peak, got 34" of snow in the
last 24 hours, 216" so far, and the snow season has just begun. They
get 80 feet in a good year.

Our summer water supply is mostly snowmelt from the mountains.

We're expecting another few big "atomospheric rivers" this week. Once
the ground saturates, we get floods and landslides. We have a lot of
non-native eucalyptus trees which get very tall and tend to fall over
when it rains.

Jeremy Renner severely injured himself plowing snow around his ranch in Lake Tahoe area. Looks they got about 5ft. A snow drift must have fooled him, covering up a steep embankment enough to lure him in and roll his truck more or less violently.

It's not too bad for us. We are near the Ukrainian Hill (refuse to use the R word) area. Unfortunately, the chargers are at the opposite side of the hill. Even brake/regen does not recover all the energy uphill. No big deal, but i usually go around the hill.
