10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksgx 151751 afdsgx area forecast discussion national weather service san diego ca 951 am pst Thu nov 15 2018 Synopsis Santa ana winds will continue to weaken today. Inland areas will warm today and Friday while cooling near the coast today spreads into the valleys on Friday. Patchy night and morning low clouds and fog may return near the coast with a greater return expected for the weekend. A weakening low pressure system is expected to move inland across southern california and northern baja on Tuesday, bringing more cooling and a deeper marine layer. Precipitation from this system is not expected at this time. Discussion For extreme southwestern california including orange... san diego... Western riverside and southwestern san bernardino counties... Update... still having isolated gusts 35-45 mph along the coastal mountain slopes in san diego county this morning. However, these winds will continue to weaken today. Relative humidity values will continue critical away from the coast, with minimum values running in the 8-12% at most inland locations today. Sunny skies will prevail today with some thin high cirrus clouds spreading in from the west. This could make for a nice sunset this evening! the high level cirrus will increase tonight. The marine layer will make its first try into the coast tonight as the surface pressure gradient transitions from offshore to neutral. It is questionable on whether or not any fog or low clouds will move onshore. There is higher confidence on fog, possibly dense, near the coast Friday night-Saturday morning as onshore pressure gradient returns. Previous discussion (issued at 328 am pst Thu nov 15 2018)... Short term (today through Saturday) Stronger and gusty east to northeast winds continue along the coastal mountain slopes into the inland valleys of san diego county, in the inland empire below the cajon and banning passes, and near and along the coastal slopes of the santa ana mountains. As expected, the winds are not as widespread and not as strong as those of 24 hours ago. Gusts in the windier locations are mostly less than 50 mph. These winds are expected to continue into this morning, then diminish during the afternoon. The lower level flow will become weakly onshore on Friday and a little stronger onshore on Saturday with a weak coastal eddy during the night and morning hours. High temperatures will begin to cool near the coast today and will warm from the valleys inland. Cooling will spread into coastal and valley areas on Friday and continue on Saturday for those areas and spread farther inland. |
Patchy low clouds and fog may return near the coast late tonight into Friday morning with a greater return near the coast for Friday night into Saturday. Some of that patchy fog for late tonight into Friday morning could be locally dense. Long term (Sunday through Wednesday) A pattern change across the eastern pacific into the western states will be underway. High pressure near the california coast will change little or weaken slightly for Sunday and Monday. A weak upper level closed low pressure system over the eastern pacific will weaken and move inland across southern california and northern baja on Tuesday. Precipitation associated with this weakening low pressure system is expected to mostly dissipate before moving inland with only very small chances for a period of light precipitation on Tuesday. Otherwise, it will bring more cooling for Tuesday and Wednesday and deepening of the marine layer. Aviation 151730z... Gradually increasing high clouds around 20000 feet msl with unrestricted vis through Friday morning. Light and variable winds through the period. Marine No hazardous marine weather through Monday. Patchy dense fog is possible, but not probable, in the coastal waters Friday morning. Fire weather Wind gusts along the coastal mountain slopes and through below passes are in the 30-40 mph range, highest along the san diego county coastal mountain slopes with MAX gusts this morning near 45 mph. These winds will subside over the next couple of hours. However, critically low relative humidity will continue today away from the coast with most locales having minimum rh values in the 8-12% range. The lower level flow will go weakly onshore on Friday and strengthen slightly on Saturday. This will spread cooling and higher coastal humidity inland with a greater overnight recovery. Weak offshore flow may return for inland areas for late Saturday night into Sunday morning and late Sunday night into Monday morning with gusty east to northeast winds mostly 30 mph or less near the coastal slopes of the mountains and below passes and canyons. The humidity for those areas could fall to around 15 percent at times, mainly during the late morning into the afternoon on Sunday and Monday. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. Sgx watches warnings advisories Ca... None. Pz... None. Public...

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
