(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 241021 afdlox area forecast discussion national weather service los angeles oxnard ca 321 am pdt Sat aug 24 2019 Synopsis 24 258 am. High pressure building over the next few days will allow for near normal high temperatures today then gradually trend higher through the weekend into early next week. Expect night through morning low clouds and patchy fog across coastal areas and santa ynez valley through early next week. There is a lower chance that some stratus could move into some coastal valleys across los angeles and ventura counties. Short term (tdy-mon) 24 258 am. Quite a difference from yesterday at this time when low clouds were covering all coast and valleys. In fact yesterday's high at paso robles only reached 79 which tied the lowest high temperature for that date. Overall is was cooler than normal for this time of year. However, today will high temps trend 3-10 degrees warmer. Latest fog product imagery indicated clear skies for areas N of point conception. To the south, only random patchy low clouds were developing along some beaches adjacent to the santa monica bay in l.A. County and across the santa barbara south coast. The lax-dag gradient was weaker at +2.7mb compared to +4.3mb 24 hours earlier. Have kept patchy low clouds in the forecast for coastal areas but should remain limited to beach cities. There is a chance that skies could remain clear across l.A. And ventura coastal areas. The marine layer was around 1500 ft deep at 2 am near lax. Although the marine layer is this deep, coastal valleys should remain sunny. The inversion is very weak however, so would not be shocked if a few patchy low clouds developed later this morning briefly. Synoptically, high pressure aloft (592-594dm) will be building in from the eastern pac and stretching across much of california and over utah az. This NW to SE elongated high will persist over the area through the short term (today-mon). The combination of increasing h5 heights and continued moderate onshore flow will cause high temps to trend up today, then more gradually on sun mon. Highs inland should be a few degrees above normal for the most part. Not expecting heat records. As high pressure strengthens overhead, subsidence aloft will help to lower the marine layer depth to between 800-1200 ft. Night through morning low clouds should become more widespread in areal coverage tonight across most coastal areas and the santa ynez valley. Have left stratus out of the forecast for the la vtu county valleys, but it's not out of the question that portions of the san gabriel could be affected during the late night and early morning hours through Monday. The only area expecting to reach 100 degrees will be the antelope valley while most valleys will range from the mid 80s to mid 90s. Paso robles should be near 90. High temps will trend up another 2-5 degrees in most locations except the salinas river valley will heat up to the upper 90s and possibly reaching 100 at paso robles. The latest on tropical storm ivo... As of 2 am pdt the location was 390 miles wsw of the southern tip of baja ca. Ivo will continue to weaken as it continues to move nnw parallel to baja. Ivo is expected to be downgraded to a tropical depression sometime late tonight into Sunday morning as it continues to enter cooler waters. The strong high pressure over southern cal will cause ivo to turn west away from southern cal. The only affect for southern california will be surf related. See the "beach discussion" below for more details. There will be some high clouds moving across portions of the forecast area from remnants of ivo Sunday night into Monday. Long term (tue-fri) 24 316 am. High pressure will will continue to dominate the weather pattern through the extended period. With onshore gradients expected to remain moderately strong, high temps should remain slightly above seasonal norms through the extended period (tue-fri). Not expecting any high cloud remnants from ivo any longer as models keep north of the area as it gets picked up in the westerlies on tue wed. There will continue to be night through morning low clouds across most coastal areas and santa ynez valley through |
the period, otherwise mostly clear. Maybe a slight chance for stratus to squeeze into the san gabriel vally tue-thu. Aviation 24 0050z. At 2345z at klax, the marine layer was 1400 ft deep. The top of the inversion was 3600 feet with a temperature of 24 c. High confidence in kpmd and kwjf tafs. Low confidence in remainder of tafs. Low cloud arrival time could be off by as much as 3 hours and there is a 20 percent chc of no low clouds at any given site. Sites with MVFR CIGS fcst have a 30 percent chc of ifr cigs. Clearing time could be off by + - 2 hours. Klax... Low confidence in taf. Low cloud arrival time could be anytime between 07z and 11z. There is a 20 percent chc of no low clouds at all.VFR transition could occur any time between 15z and 19z. Good confidence that there will be no east wind component greater than 3 kt. Kbur... Low confidence in taf. Low cloud arrival time could be anytime between 09z and 13z. There is a 30 percent chc of no low clouds at all.VFR transition could occur any time between 15z and 17z. Marine 24 308 am. For all the coastal waters, high confidence in current forecast. Today through Wednesday, winds and seas are expected to remain below small craft advisory (sca) levels. A large southeast to south swell from tropical storm ivo will affect the waters Sunday through Tuesday. Swell will likely peak between 4 and 5 feet, with a slight chance of swell peaking between 5 and 7 feet. A swell from this direction would cause strong surges around and inside the vulnerable harbors, especially avalon and san pedro long beach. Large breaking waves near the coast are also likely, which has a history of capsizing small drifting boats. Beaches 24 308 am. Tropical storm ivo, currently about 300 miles wsw of cabo san lucas, will generate a southeasterly to southerly swell which will reach the coastal waters california Sunday and persist through Tuesday. The peak of the swell should occur Sunday afternoon through Monday morning with a period around 14 seconds. The peak of the swell heights will most likely fall between 4 and 5 feet, with a slight chance of swell heights reaching 5 to 7 feet. Dangerous rip currents and large breaking waves on rock jetties are certain. Surf heights should reach at least 4 to 6 feet over south facing beaches, with a chance of peak surf reaching 6 to 8 feet especially for los angeles county, which would require a high surf advisory. There is a risk of some coastal flooding as well. The highest tides will be late in the afternoon, and should reach 5.7 to 6.7 feet. If the peak swell ends up between 4 and 5 feet as expected, flooding impacts would be mostly minor and mainly in the form of beach erosion and minor overflow. If the swell heights ends up in the 5 to 7 foot range, which is much less likely, more impactful flooding would be expected for vulnerable areas like pebbly beach in avalon and unprotected parts of the long beach peninsula. Lox watches warnings advisories Ca... Beach hazards statement in effect from late tonight through Tuesday morning for zones 40-41-87. (see laxcfwlox). Pz... None.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
