Hydrologic Outlook
National Weather Service Sacramento CA
1220 PM PST Sun Dec 25 2022

…Moderate to heavy rain will likely cause some urban and small
stream flooding late Monday through Tuesday…

* WHAT…A significant winter storm will impact the region late
Monday and Tuesday, with showers lingering into Wednesday. This
potent system is tapping into a very moist subtropical plume,
which will allow for periods of moderate to heavy precipitation.
Precipitation will begin in the Northern areas Monday evening,
becoming moderate to heavy Monday night, then spread south
across the region early on Tuesday. Rainfall totals will range
from 1.00 to 2.5 inches in the valley, with foothills and
mountains receiving 2.5 to 4.5 inches. Locally up to 6 inches
are possible over favored southwest facing peaks. Moderate to
heavy rain will lead to rapid rises of area rivers, streams, and
creeks. Localized ponding of water for low-lying or poorly
drained areas as well as localized flooding is possible due to
blocked drainages, and storm drains. Main stem rivers are
forecast to remain well below flood stage, but may rise above
monitor stage in a few locations.

* WHERE…Interior Northern California

* WHEN…Monday night through Tuesday with greatest impacts
expected early Tuesday. Showers will linger through Wednesday,
with runoff expected to continue.

* ADDITIONAL DETAILS…There is a concern for minor mud, rock, and
debris flows that may occur across burn areas. In addition,
strong and gusty winds are expected late Monday night and
Tuesday. Debris from gusty winds may cause drainage blockages
which could create a localized flooding threat. Localized
ponding of water is likely in low-lying or poorly drained areas,
such as freeway off ramps. No mainstem river flooding is
forecast at this time, but mainstream rivers will see rapid
rises, and may reach monitor stage in a few places. More storms
look likely late this week and into the early part of the New
Year. Please monitor the latest forecast for the most up to date
weather information.
