Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
254 AM PST Wed Dec 24 2025

.SYNOPSIS...24/1250 AM.

A powerful winter storm will bring heavy rain and strong winds to
the area through Christmas Day. Significant flooding issues and
strong winds are expected along with the potential for strong
thunderstorms. For Friday and Saturday, a cool and showery pattern
will persist. Dry conditions are likely Sunday and Monday.

&&

.SHORT TERM (TDY-FRI)...24/227 AM.

***STRONG ATMOSPHERIC WINTER STORM WITH DANGEROUS FLOODING AND
 ROCK/MUD SLIDES TONIGHT THROUGH THURSDAY EVENING***

The AR system has tilted into a SSE to NNE direction and is aimed
at SBA county. This is a few hours slower than previously forecast
and while rainfall amounts and intensity forecasts have not
changed peak timing is now 2 to 3 hours later than previously
thought. Peak rainfall timing for SBA county is now 3 to 7am; VTA
county 5am to 1pm and LA county 9am to 4pm. SLO county will be
wet but will not see significant rainfall rates over a half per
hour. All mdls now show a significant brake in the major rainfall
action from this evening through early Christmas morning when a
cold front will sweep through the area starting over the Central
Coast in the morning; southern SBA county and VTA county either
late morning or early afternoon and LA county may be mostly dry
through at least mid afternoon. A 20 to 30 chc of showers will
persist through this quiet period but its unlikely that there will
be any large scale organization. The latest RRFS run shows a
generous uptick in shower activity over VTA and esp LA counties
late Thursday into Friday morning. This second system has more
cold air with it and a better chc for convection. There should be
a noticeable decrease in shower activity in the wake of the front
Friday afternoon (earlier across the Central Coast). The Flood
Watch was extended to Friday afternoon to account for the
convective bursts from the front.

Max temps will be pretty typical for a December storm with highs
across the csts and vlys a couple of degrees either side of 60.

RAIN TOTALS:

TODAY Through 10pm:

North of Point Conception: 1-2 inches coastal/valley areas and
2-3 inches for foothills/mountains.

South of Point Conception: 2-4 inches coastal/valley areas and
4-9 inches foothills/mountains.

TODAY THROUGH FRIDAY:
North of Point Conception: 2-4 inches coastal/valley areas and
4-7 inches for foothills/mountains.

South of Point Conception: 4-7 inches coastal/valley areas and
6-14 inches foothills/mountains.

RAIN RATES: Peak rainfall rates north of Point Conception are
expected to be in the 0.40-1.00 inch/hour range. South of Point
Conception, rainfall rates are expected to be higher (0.70-1.50
inches per hour), especially on south-facing slopes.

THUNDERSTORMS: Unstable air, associated with the storm, along with
strong jet dynamics will bring a chance of of embedded
thunderstorms tonight through Thursday evening to all areas. The
STORM PREDICTION CENTER placed the area under a marginal risk of
severe thunderstorms tonight through Christmas Day. Any
thunderstorms that form will bring brief intense rainfall. More
importantly, due to the strong upper level winds, any convective
element will have a high risk to bring damaging winds.
Additionally, there will be a chance of weak, short-lived,
tornadoes or waterspouts, especially during the second wave of
energy on Thursday when there is colder air aloft and more
instability.

SNOW: Snow levels will remain above the 7500-8000 foot range
through Christmas Eve, but will drop to the 6500-7000 foot range
on Christmas Day and down to the 5500-6000 foot range on Friday.
So, no winter weather issues are expected through Christmas Eve,
but some decent accumulating snowfall will be likely at the resort
level beginning on Christmas Day.

WIND: Strong and gusty southeast to south winds are expected
today through Christmas Day. Warning level wind gusts, 60-80 MPH,
are likely across San Luis Obispo and Santa Barbara counties as
well as the Ventura/LA mountains and Antelope Valley. Elsewhere,
strong advisory-level winds, gusting 35-55 MPH, are expected. HIGH
WIND WARNINGS and WIND ADVISORIES remain in effect.

IMPACTS: Widespread and significant urban flooding will be likely
along with rock/mudslides and debris flows (with the threat not
just confined to burn areas). Streams, rivers, and creeks will
also see rapid flows, thereby increasing the threat of swift water
rescues and there is a possibility of some localized river
flooding. A FLOOD WATCH IS IN EFFECT FOR ALL AREAS OF SOUTHWEST
CALIFORNIA DUE TO THESE MAJOR HYDROLOGICAL RISKS. The combination
of increasingly saturated soil and the strong winds will bring the
potential for widespread downed trees and power lines, especially
in areas under a High Wind Warning.

ONCE AGAIN, THIS IS A VERY DANGEROUS HOLIDAY STORM. ANYONE
TRAVELING ON CHRISTMAS EVE OR CHRISTMAS DAY WILL NEED TO EXERCISE
EXTREME CAUTION. MAKE SURE TO TAKE THE PROPER PROTECTIVE ACTIONS
BEFORE THE STORM HITS.

.LONG TERM (SAT-TUE)...24/1249 AM.

The trof will sweep out the area Saturday morning. Scattered
showers will cover the area in the morning but then diminish and
end in the afternoon as the NVA enters the area behind the trof.
Rainfall amounts will not be that homogeneous but will likely all
be under a quarter inch. Snow levels will be near 5000 ft so some
fairly low level accumulations are possible. Below normal temps
will continue with max temps coming in a few degrees either side
of 60.

Not much synoptic agreement on the Sunday upper pattern. But no
mdl is showing any rain and hgts a fairly similar so do not think
the mdl disagreement will affect the fcst too much. The big news
is that for the first time in a while skies will be mostly sunny
or at worst partly cloudy. Max temps will bump up 3 to 6 degrees
with the sunshine and most cst/vly max temps will be near 65
degrees.

Mdl disagreement worsens on Monday, but at least the ensembles
have trended toward the dry deterministic runs and now it looks
like Monday will be dry. Max temps will rise another 2 to 4
degrees and most max temps across the csts/vlys will be in the mid
to upper 60s.

Most ensembles show an upper low moving into the area from the
south. This will increase the clouds and bring a slight chc to chc
of rain to the area as well as cooler temps.

&&

.AVIATION...24/0649Z.

At 0515Z at KLAX, there was no marine layer nor an inversion.
There was a 8000 ft deep moist layer.

Low confidence in all TAFs through the period. Cigs and Vis will
vary frequently as rain moves through the area. Fair confidence
with improving conditions after 25/00Z esp west of LA county.

There is a 10-15 percent chc of TSTMs through the period.

Strong winds will affect most airfields through 25/00Z and sites
north of Pt Conception will be affected through Friday. The winds
will generate turbulence over and near to hier trrn.

KLAX...Low confidence in TAF. Cigs and Vis will vary frequently
as rain moves through the area. There is a 10 percent chc of a
TSTM through the period. Good confidence that there will be an
east wind component over 10kt through at least 25/00Z with a 40
percent chc it extending to 15/10Z.

KBUR...Low confidence in TAF. Cigs and Vis will vary frequently
as rain moves through the area. There is a 10 percent chc of a
TSTM through the period. The strong winds will generate periods of
turbc and LLWS.

&&

.MARINE...24/237 AM.

A powerful winter storm will bring widespread, dangerous marine
weather to the coastal waters with strong winds, rough short-
period seas, heavy rain, and a chance for thunderstorms today through
Thursday.

Vessels, especially small vessels, are strongly advised to remain
in safe harbor for the duration of the storm, as these conditions
can sink boats. South-facing harbors will also be especially
vulnerable to the south swell and strong winds.

Details:
South to southeast winds and seas to dangerous levels will affect
the waters tonight. High-end GALE conditions are expected, likely
strongest north of Point Conception. These strong winds are
expected to affect the nearshore waters, especially for
unsheltered south-facing coastlines and areas north of Point
Conception.

Large southerly short-period seas will occur Today and Thursday,
leading to elevated, choppy seas at south-facing harbor entrances.
There is also a 15-30% chance of thunderstorms tonight through
early Thursday, which will bring a threat of erratic gusty winds,
heavy downpours, cloud-to-water lightning and a small chance of
waterspouts.

&&

.BEACHES...24/239 AM.

A short to moderate period southerly wind swell will produce
choppy, large, dangerous surf and rip currents through Thursday.
A longer period NW swell will take over Friday, and surf will
continue to be significant into the weekend. It is best to remain
out of the water during this time. See High Surf Advisory (CFWLOX)
for details.

While peak tides are not very high, minor to locally moderate
coastal flooding may occur for south facing shores through
Thursday.
