Low clouds will push back inland after 01Z Sat and fill in the coastal basin. Bases will be 1500-2500 ft MSL, with the most likely places for the bases to fall below 2000 ft are at KCRQ and near mtn foothills (70 percent). Chances of visibility falling below 3SM is around 70 percent near mountain foothills. Patchy -DZ possible from 09-18Z. Slow clearing expected Sat AM with SCT conditions most likely after 18Z for most locations.
Mountains/Deserts, Elevated westerly wind gusts 25-40 kt after 21z today with MOD up/downdrafts and local LLWS in lee of mountains. Localized areas of BLDU and reduced VIS. Winds will remain gusty through much of Saturday. Otherwise, SKC and VFR expected through the period.
Gusty westerly winds with gusts 20-30 kt will develop in the outer coastal waters late Saturday afternoon. The strongest gusts will occur near San Clemente Island. Seas of 8-11 feet with a 9-12 second period will generate choppy seas. Winds and seas will diminish through the day Sunday.
A westerly swell from 290 degrees with a 9 to 10 second period will bring elevated surf of 4 to 6 feet, sets to 7 feet for Saturday afternoon through Monday morning. Highest surf at west to northwest facing beaches. The combination of elevated surf and high tides of 6.5 to 7 feet will result in minor tidal overflow, especially for beach parking lots and boardwalks. Surf will start to decrease Monday afternoon.
