High Surf Advisory
Statement as of 1:27 PM PDT on July 18, 2008
... High surf advisory in effect from 9 PM Saturday to 2 am PDT
Tuesday...
The National Weather Service in San Diego has issued a high surf
advisory... which is in effect from 9 PM Saturday to 2 am PDT
Tuesday.
Fairly large long period south swells originating from storms in
the southern hemisphere will move into the coastal waters off
Orange County over the weekend. This will bring high surf to the
beaches of Orange County late Saturday evening through Monday
night. Surf of 5 to 7 feet with larger sets to 9 feet are expected
during this period.
A high surf advisory means that high surf will affect beaches in
the advisory area... producing rip currents and localized beach
erosion.

NWS Forecaster Discussion
312 fxus66 ksgx 182101 afdsgx Area forecast discussion National Weather Service San Diego California 200 PM PDT Friday Jul 18 2008 Synopsis... high pressure temporarily building over the area will lower the marine layer tonight. However fog is likely to be more widespread and affect the coastal mesas and lower western valleys tonight through middle Saturday morning. Otherwise pleasant weather is expected for Saturday. However a strong surge of monsoon moisture Saturday night into Sunday will bring a return of thunderstorms over the mountains and deserts that will continue into Monday. Some of the showers and thunderstorms move west across the valleys and reach the coast Sunday evening. && Discussion...for extreme southwestern California including Orange... San Diego...western Riverside and southwestern San Bernardino counties... Short term...tonight through Monday... three weather concerns for southwest California during this period are the depth of the marine layer and stratus burn off/return times...the renewed surge of monsoon moisture...and the building south swell. Marine layer increased slightly this morning to around 2200 feet. The high pressure ridge...whose axis is shifting southward across the area through tonight should cause the subsidence inversion to lower and strengthen a little more before weakening on Saturday. Based on nam12 model cross section trends after baselining to this mornings observations...marine layer depth expected to lower to 1500 feet this evening and to around 1000 feet by Saturday morning. Cross sections show layer mean relative humidity 96-100 percent so thick stratus cloud layer likely with more of the lower valleys/coastal mesas impacted by dense fog late evening/overnight. For Saturday night/Sunday moist unstable air mass aloft expected to inhibit stratus formation...see below. The next weather problem to address is the return of monsoon moisture this weekend. The remnants of a large mesoscale convective complex are sitting over the southern Gulf of California poised to be drawn northwestward. With the upper trough approaching the northern/central California coast today and pushing slowly inland Saturday and Sunday...a cleft in the ridge is made for this moisture to be pulled up. Models all show southeast developing aloft on Saturday with strong southeast flow...25-40 kts...in the low levels up the Gulf of California. Strong surge of monsoon moisture moving across Salton Sea/Coachella Valley/Morongo Valley/Yucca Valley and into Johnson/Lucerne valleys expected Saturday evening. Only thing that might inhibit convection on Sunday would be extensive debris clouds from Saturday nights convection. Have tweaked the weather/pop/and sky cover grids to add chance of thundershowers for Saturday evening over Lower Desert areas and sprinkles for early Sunday morning over mountains/deserts for dissipating overnight convection...as well as upped probability of precipitation/quantitative precipitation forecast amounts Sunday evening over areas west of the mountains. Third problem...wamiii model is known for flattening amplitude and missing timing of arriving southern hemisphere swells. It usually gets the direction and the period correct though. The relatively steep approach angle...190 degrees...means Orange County and only a few parts of San Diego County will be affected. The long period indicates a significant amount of shoaling will occur with surf heights easily double the swell height on beaches with steep slope and directly facing the arriving swell. Relaying strictly on model guidance will likely result in underforecasting of surf heights at these beaches but probably overforecasting at the west facing beaches since most of the swell energy will pass by to the north and only a third to a quarter of it will be refracted towards these beaches. && Long term Tuesday through Friday... backed off on threat of thunderstorms Tuesday and Wednesday over the mountains/deserts but left in for Thursday and beyond. GFS model for at least last four runs has been showing drying southwest flow returning Tuesday and Wednesday in the 850-700 mb layer. After which southeast flow returns as another tropical wave passes by to the south. A very shallow and disrupted marine layer will bring night and morning clouds and fog to coastal strip and lower western valleys but expect onset to be later and clearing times earlier. && Aviation... 181915z...mdcrs soundings continue to show the marine layer depth to be around 2000 feet. Expect little change in the marine layer depth through the weekend. A weak coastal eddy should help maintain the marine layer through the weekend. Stratus with bases around 1400 feet mean sea level along the immediate coast should spread back inland over the coastal valley and mesas between sunset and 04z and the western inland valley areas before midnight. Stratus should reach vicinity of kont between midnight and sunrise on Saturday. Breakup on Saturday should be between 16z and 18z. Above the marine layer...except for some afternoon cumulus/towering cumulus over the mountains during the afternoons...a mostly clear sky with unrestricted visibilities will continue through Saturday. Middle and high level moisture moving in from the southeast Saturday night and Sunday could bring thunderstorms to the mountains and deserts on Sunday. Maximum temperatures for kpsp and ktrm for Sat...42 to 44c. Horton && Marine... a moderate south swell will begin to move into the coastal areas today...increasing through Sunday. The period will increase to 19 seconds on Saturday with the peak of the swell expected on Sunday with a period dropping to 16 seconds by Sunday afternoon. Surf is forecast to be up to 3 to 6 feet on Saturday with sets to 9 feet or higher mainly in Orange County Sunday. A high surf advisory will be issued for the Orange County beaches for Saturday night through Monday night. There will be strong and dangerous rip currents during the weekend. && Sgx watches/warnings/advisories... California...high surf advisory from 9 PM Saturday to 2 am PDT Tuesday for Orange County coastal areas. Quantitative precipitation forecast...qpssgx issued 122 PM PDT for rainfall estimates through Sunday evening Special Weather Statement...spssgx...issued at 116 PM PDT for rainfall and flash flood potential. Also refer to latest hazardous weather outlook. Pz...none. && $$ Public...Balfour aviation/marine...Horton National Weather Service on the web at weather.Gov/sandiego
