| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 742pm PDT Tuesday September 1 2026 Synopsis 01/136 AM. Stagnant pattern through Friday, with below normal temperatures, patchy marine layer clouds, and moderate Sundowner winds. Several potential scenarios for the Labor Day weekend, with anything from benign conditions, tropical rain, or even hot offshore winds. Short Term - Tuesday through Friday 01/153 PM. Overall, 12Z models in good synoptic agreement through the short term period. At upper levels, a trough will remain over the West Coast, varying in strength from day-to-day. At the surface, moderate onshore flow will continue to the east with some offshore flow from the north. With this pattern, relatively benign weather is expected for the area. Main concern will be winds, specifically Sundowner winds, across southern Santa Barbara county. High resolution models indicate stronger SBA-SMX gradients tonight which will produce stronger winds across the western Santa Ynez Range and will likely hit advisory-levels overnight. So, have issued a WIND ADVISORY for the western Santa Ynez Range and adjacent coastal strip through 600am Wednesday morning. Based on SBA-BFL gradient, there may be some gusty winds across the eastern Santa Ynez Range (Montecito area), but advisory-level winds are expected at this time. For Wednesday night, models indicate even a bit strong northerly flow, so advisory-level winds will likely continue across southern Santa Barbara county. As for clouds, there will be some marine layer stratus/fog each night and morning across the coastal plain and some coastal valleys, due to the onshore flow and potential eddy circulations. However, confidence in areal coverage each night remains low. Other than any stratus/fog, skies should remain mostly clear through Friday. Finally for temperatures, there will only be minor day-to-day changes, based on the whims of the marine influence and changes in H5 heights. For most areas, high temperatures will remain about 2-6 degrees below seasonal normals. Long Term - Saturday through Tuesday 01/153 PM. For the extended, an upper low is forecast to wobble over and around the Pacific Northwest through the Labor Day weekend. Models vary on the exact path of the wobble, but cyclonic flow aloft will remain over the area through early next week. At the surface, focus remains on current Tropical Storm Marie. Currently, Marie is located around 15N 109W and the latest forecast from the National Hurricane Center have Marie intensifying to hurricane strength on Wednesday, following a track to the northwest through the Labor Day weekend. The chances of Marie directly hitting Southern California as a hurricane or tropical storm remain VERY LOW (with only a few ensemble members from the models indicate any track close to Southern California). However, despite the HIGH likelihood of Marie maintaining a west to northwest track away from the West Coast, there still be some noticeable impacts for the area from this storm. With the upper level pattern, moisture from Marie will be advected over the area during the Labor Day weekend, but the amount of moisture will be greatly impacted by the exact track of the hurricane. At this time, there is a 50-60% chance of widespread light rainfall (amounts 0.10-0.50 inches) Sunday through Tuesday and about a 10-15% chance of heavy rainfall and thunderstorms. As for winds, there will be about a 10-15% chance of moderate to strong easterly winds ahead of any rainfall which could produce some fire weather concerns. Finally, there is high confidence in significant coastal risks which are detailed in the Marine and Beaches segments of this discussion. Needless to say, the weather for the upcoming Labor Day weekend may by highly dynamic. A minor change in the track of Marie could result in significant changes to the current forecast. So, given the uncertainty with this pattern, stay tuned and monitor the latest forecasts. Marine 01/255 PM. Moderate to high confidence for Small Craft Advisory (SCA) level winds and short- period seas across the southern Outer Waters today through Friday, with a 30-40% chance of SCA (Small Craft Advisory) level winds extending to the inner and outer waters north of Point Sal (greatest chance in the afternoon/evenings). For Saturday, there is a 30-40% chance of SCA (Small Craft Advisory) level wind across all of the Outer Waters. Today through Thursday evenings, there is a 50-80% chance of SCA (Small Craft Advisory) level winds across the Santa Barbara Channel, and a 30% chance of local SCA (Small Craft Advisory) winds for the inner waters off the coast of LA and Orange Counties Wednesday evening. Expecting increasing southerly swell this weekend due to tropical activity to the south. The details and timing are very much dependent on the track of the soon to be formed tropical cyclone, but confidence is moderate to high that the coastal waters will see a larger than normal in southerly swell over Labor Day Weekend. Beaches 01/300 PM. While there remains a range of outcomes in terms of the track of Tropical Cyclone Marie, SoCal is likely to see an increasing southerly-southeasterly swell this weekend into Tuesday (which may combine with the swells from the current Hurricane Karina). This most likely scenario would result in high surf advisories for south facing beaches (Avalon, Long Beach Peninsula, Malibu, Point Mugu) during a busy holiday weekend (especially Sunday into Monday night), with very strong rip currents. Additionally, evening high tides are expected to be around 7 feet during portions of the event. As a result, there is an increasing chance of moderate coastal flooding of low- lying areas and significant beach erosion. There is a chance that coastal flood advisories will be issued. NOAA Los Angeles/Oxnard CA Office: Watches - Warnings - Advisories CA...Wind Advisory in effect until 6am PDT Wednesday for zones 349-351. PZ...Small Craft Advisory in effect until 3am PDT Wednesday for zone 650. Small Craft Advisory in effect until 3am PDT Thursday for zones 673-676. https://www.weather.gov/erh/ghwo?wfo=lox |
