Strong westerly swell (9-11 feet with an average period of about 10-
12 seconds) will produce large breaking waves up to 8-12 feet on
most beaches across Orange and San Diego Counties today through
Friday night. Widespread, strong rip currents are also likely with
these waves and dangerous swimming conditions expected. A High Surf
Advisory is in effect and contains more information.

&&

.HYDROLOGY...
A winter storm will bring widespread moderate to heavy
precipitation and mountain snow from late this morning through
this afternoon, followed by scattered showers into early Tuesday
morning along with a slight chance of thunderstorms tonight.
Another round of more widespread precipitation with lower snow
levels is expected for Tuesday night into Wednesday morning.
Additional light showers are possible Thursday into early Friday.
Precipitation chances are currently below 15 percent for Friday
and Saturday, but there is the potential for light showers at
times.

Peak hourly rainfall rates during the frontal passage today will
range from 0.50-0.75 inch per hour, mostly between 10 AM and 4 PM.
Rainfall and liquid-equivalent above the snow level for today
through Tuesday morning will range from around 1 to 1.5 inch for
coastal areas to 2.5 to 3.5 inches in the mountains with locally
greater amounts. For the deserts, 0.50 to 1 inch is expected for
the Apple and Lucerne Valleys with 0.15 to 0.50 inch for the lower
deserts.

The snow level will rise to 6500 to 7500 feet late this morning
and early this afternoon, then fall to 5000 to 5500 feet for late
this evening and 4500 to 5500 feet for Tuesday morning. Snowfall
of 4 to 8 inches is expected from 5500 to 6000 feet, 8 to 14
inches from 6000 to 7000 feet, and locally 2 to 3 feet above 7500
feet.

Additional rainfall and liquid-equivalent above the snow level

6000 feet, 6 to 12 inches from 6000 to 7000 feet, and 12 to 18
inches above 7000 feet.

If higher-end rainfall amounts materialize across the northern
Coachella Valley, increased flows on the Whitewater River could
cause flooding at some of the low-water crossings. Latest river
forecast ensembles have around a 15 percent chance of the San
Diego River reaching Monitor Stage for late today and on
Wednesday.
