Although rain and mountain snow are expected to wind down by
Sunday, another atmospheric river will bring additional rounds of
heavy rainfall and mountain snow on Monday. With overly saturated
conditions still in place, further limited flooding impacts are
expected across California into Monday. Meanwhile in the
mountains, heavy mountain snow and strong winds will lead to
blowing snow and whiteout conditions at times, creating dangerous
to near impossible travel above 4000 ft in the mountains and
passes of central and southern California.

The next Storm Summary will be issued by the Weather Prediction
Center at 700 AM PST. Please refer to your local National Weather
Service office for additional information on this event.
