| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 838pm PST Sunday Dec 28 2025 Synopsis 28/725 PM. The weekend will be dry and warmer across coastal/valley areas. A moderate to strong Santa Ana wind event is expected tonight through Monday with some lingering northeast winds into Tuesday. Periods of light to moderate rain will likely impact the region by Wednesday or Wednesday night. Short Term - Sunday through Wednesday 28/720 PM. With increasing Santa Ana winds, most areas will be mostly clear tonight, with the exception of the interior valleys of San LUis Obispo county where some low clouds and fog will impact the area. As of 7 pm, Santa Ana winds already ramping up in speed and coverage, with many areas seeing wind gusts in the 35 to 55 mph range, except isolated gusts to 60 mph in favored mountain areas. The current LAX-Daggett gradient is at -5.4 mb and is expected to peak in the -7 to -8 mb range by Monday morning. This offshore pressure gradient combined with increasing upper level wind support (950 to 850 mb winds in the 40-50 knot range) will likely cause a further increase in wind speeds tonight into Monday. High wind warnings are in effect during this period for the I-5 corridor, western San Gabriels, western Santa Monicas, and Santa Susanas, where damaging wind gusts up to 65 mph will be likely. For remaining wind prone areas of LA/Ventura counties, wind advisories are in effect through Monday where gusts of 35 to 55 mph will be common, with hardest hit area likely to be the Highway 118 corridor near Simi Valley/Moorpark, and extending to Camarillo. In evening update, will be adding eastern San Fernando Valley and southern Ventura mountains to wind advisory. The gusty Santa Ana winds will create a higher than normal risk of downed trees due to the recent heavy rains making the soils very wet. Santa Ana winds will continue into Tuesday with with less support aloft and gradients starting to trend onshore winds are expected to be at least 10-15 mph weaker on Tuesday as compared to Monday. ***From previous discussion*** Santa Ana winds are also known for creating very warm temperatures due to the downsloping effects off the mountains but in this case there is quite a bit of cold air advection that will likely minimize the warming, especially inland. Coastal areas will likely be the warmest, but probably only topping out in the lower or possibly mid 70s. Most valleys and inland areas will be in the 60s at most. Cold advection will be weakening Tuesday so there should be at least a few degrees of warming inland. Starting on Wednesday moisture from off the coast of Mexico will be moving into the area and rain chances will return by Wednesday evening, if not sooner. The latest NAM is quite a bit faster with the moisture advection, suggesting rain beginning as early as Wednesday morning, while most of the ensembles hold off until Wednesday afternoon or evening. In any case, it does look like 2026 will start off wet across all of southern California. Long Term - Thursday through Sunday 28/223 PM. Looks like at least 2-3 days of off and on rain showers to start the New Year, the heaviest of which being New Years Day and then again Friday night into Saturday when the upper low from the northwest merges with the moisture advection from the south. In between those times rain rates appear to be on the lighter side, mostly under a quarter inch per hour, and not raining all the time. Heavier rain expected on at the beginning and end of the event, though there is still a lot of uncertainty in the models with timing and rates. For the time being the forecast is calling for 1-3" of rain across coast and valleys and 2-5" in the mountains. Snow levels will be very high initially, well over 7000 feet but then lowering to around 7000 feet at the back end of the event later Saturday. Marine 28/836 PM. Moderate to high confidence in the current forecast for winds. Less confidence in the current forecast for seas. For the nearshore waters along the Central Coast and the waters inside the southern California bight, there is a high to likely (50 to 70 percent) chance of areas of Small Craft Advisory (SCA) winds nearshore into Tuesday afternoon, except for an imminent (80-100 percent) chance of SCA (Small Craft Advisory) level winds and a likely to imminent (60-80 percent) chance of GALES from Rincon Point to Santa Monica and across the San Pedro Channel. Winds will likely diminish and drop below SCA (Small Craft Advisory) levels Tuesday afternoon through Wednesday morning, then there is a high to likely (50-70 percent) chance of widespread SCA (Small Craft Advisory) conditions developing between Wednesday afternoon and late Thursday night. Gusty southerly winds could combine with hazardous seas to create poor marine conditions. During this time period, there is a moderate (30-40 percent) chance of GALES. For the waters beyond 10 NM of the Central Coast and south to San Nicolas Island, there is a high to likely (40-60 percent) chance of SCA (Small Craft Advisory) level northeast winds affecting the closer to shore portions through Tuesday morning. Winds will likely diminish Tuesday afternoon through Wednesday morning, then there is a likely (60-80 percent) chance of widespread SCA (Small Craft Advisory) conditions developing between Wednesday afternoon and late Thursday night. Gusty southerly winds could combine with hazardous seas to create poor marine conditions. During this time period, there is a high (40-50 percent) chance of GALES.
