| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 919am PDT Sunday September 28 2025 Synopsis 28/855 AM. Cooler than normal conditions will persist through next week, but temperatures should rise a little starting Wednesday. Showers and thunderstorms are possible over the mountains and deserts this afternoon. Small chance of light rain around the Central Coast late Monday into Tuesday. Areas of drizzle possible each morning through Tuesday. Short Term - Today through Tuesday ...28/917 AM. ***UPDATE*** Marine layer remains at least 4000 this morning all the way up the coast. Not quite as much drizzle this morning as yesterday but still pretty damp near the foothills. Another slow or no clearing day for coast and valleys with temps 6-12 degrees below normal inland and 1-3 below normal near the coast. SST's in the high 60s are helping to moderate the temps near the coast. Soundings locally still indicating a fair amount of instability today with lapse rates between 7 and 8c and mucape between 1000 and 1500j/kg. The upper low has finally exited the state after a week plus vacation in southern California, and even though PW's have lowered still think there will be some isolated showers and storms this afternoon over the mountains. The hi res models are showing storm initiation in the usual areas, namely in the Frazier Park area between 1 and 2pm this afternoon and slightly later across the San Gabriels. Storms won't be as strong as yesterday and rain amounts won't likely pose any flash flooding concerns, but brief heavy rain is possible with any storms. ***From Previous Discussion*** A low pressure system currently just west of the Aleutian Islands has spawned two frontal bands that will march down the West Coast. All projections have these bands fizzling out by the time they reach Point Conception Monday or Tuesday, but 10-30% of the ensembles produce some light rain on the Central Coast. Added some slight chance wording back to the forecast as a result. Any amounts will be very light with minor impacts. The marine layer and inland low cloud intrusion remain deep and expansive through Tuesday. Expect random patches of drizzle wetting roads anywhere, with some hilly areas seeing accumulations. With the fronts approaching, the Central Coast might see enhanced drizzle Monday or Tuesday. All of this adds up to temperatures staying well below normal. No major wind concerns through at least Tuesday. Long Term - Wednesday through Saturday 28/331 AM. Dry conditions are likely Wednesday through the following weekend, with any chances of rain very minimal at this point. Temperatures will increase a few degrees as high pressure from Mexico noses northward, but temperatures will remain below normal. Some moderate Sundowners will form each night. The combination of those winds and the ridge just to the east should shrink the marine layer and force it to return to more normal operations. Marine 28/906 AM. For the Outer Waters, moderate to high confidence in current forecast. Today through Tuesday, high confidence in winds and seas remaining below Small Craft Advisory (SCA) levels. For Wednesday and Thursday, there is a 30-50% chance of SCA (Small Craft Advisory) level winds and seas. For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Today through Wednesday, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels. On Thursday, there is a 30% chance of SCA (Small Craft Advisory) level winds in the afternoon and evening hours. For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For a majority of the southern Inner Waters, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels. The only exception will be the western half of the Santa Barbara Channel with a 30-40% chance of SCA (Small Craft Advisory) level winds on Wednesday and Thursday, during the late afternoon and evening hours. Through this Wednesday, a southerly swell of 3 to 6 feet will impact the coastal waters and may produce issues for exposed south facing harbors. Beaches 28/202 AM. A moderately-long period southerly swell will develop across the coastal waters today and last into Wednesday, generated by Hurricane Narda. Hazardous rip currents and elevated surf are likely for south-facing beaches, especially across Los Angeles and Ventura Counties, as well as Avila Beach and Port San Luis for the Central Coasts. Additionally, particularly vulnerable south- facing beaches may see shallow coastal flooding over normally dry beach areas. A Beach Hazards Statement is in effect for all exposed south- facing beaches for today through Wednesday. Surf of 4 to 7 feet is expected, with local max sets up to 8 feet for the Central Coast. NOAA Los Angeles/Oxnard CA Office: Watches - Warnings - Advisories CA...Beach Hazards Statement in effect through Wednesday afternoon for zones 87-340-346-354-362-366. (See LAXCFWLOX).
