9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Temperatures will remain relatively cool across the region through Friday, then warming is expected again next weekend. Most coastal and adjacent valleys will have night to morning low clouds and fog at times this week. There will be gusty north winds west of santa barbara during the evening and overnight hours tonight through Thursday. Short term (mon-thu) 16 752 pm. ***update*** an upper trough moving inland over the west coast will lift to the northeast overnight as another upper low shifts southward from the gulf of alaska to the queen charlotte islands. Behind the departing trough, a northerly surface pressure gradient is developing, with a -3.6 mb gradient between sba and smx as of 7 pm. Gusty northwest to north winds are affecting the south coast this evening, with gusts to 35 mph at san marcos pass and 40 to 45 between gaviota and refugio. A wind advisory has been issued for the south coast and santa ynez range this evening through 3 am Tuesday. Gusty northwest winds will also affect the l.A. And ventura mountains overnight, primarily through highway 33 and the i-5 corridor, with peak gusts to around 35 mph. For coastal areas, low clouds and fog are expected along the central coast, mainly south of san luis, and along the coast of l.A. And ventura counties. Low clouds are likely to cover most of the l.A. Basin, extending into the san gabriel valley, but should stay closer to the coast in ventura county. ***from previous discussion*** the trough has already brought cooler temps to the area today with inland areas down as much as 10-15 degrees and coastal areas about 5 degrees cooler. Low clouds and fog expected to develop at most coastal locations at some point overnight tonight, if not sooner along the central coast. Southern sb county likely to remain clear due to the northerly flow. Could also see some low clouds and fog near our border with kern county from SE slo county through the i5 corridor. Offshore trends tomorrow behind the trough along with slowly warming temps aloft will lead to a warmer day most areas Tuesday by a few degrees. Another trough will hit the pac NW Wednesday and northern california Wed night into Thursday. Impacts here again mostly limited to a slight cooling trend, stronger onshore flow, and deeper marine layer. Long term (fri-mon) 16 149 pm. A warming trend will commence Friday as the trough moves east into the northern plains and surface high pressure develops over the great basin that will weaken our onshore flow. Models maintain some weak cyclonic flow across ca at least through the weekend but temps should bounce back up to normal levels by Saturday with little change into Sunday. Both the GFS and ECMWF show high pressure over the eastern pacific expanding into the west coast pushing the next trough farther east into the great basin. It's a little too far out on the horizon to have much confidence but such a track could lead to increasing offshore flow early to mid next week and even warmer temperatures. Aviation 17 0002z. At 00z, the marine layer depth was around 1200 feet deep at klax. The top of the marine inversion was near 2200 feet with a temperature of 22 degrees celsius.

For the outer waters, small craft advisory (sca) level winds are becoming more widespread this evening and likely to persist through Thursday, and continuing over the two southern zones (pzz673-676) through Friday.

A southerly swell developing with hurricane kiko will move over the coastal waters from late tonight through Wednesday. There is a 40 percent chance that elevated surf of 3 to 5 feet could break near shore and in the vicinity of jetties at times during this period mainly for the south-facing beaches in los angeles county. Beaches 16 140 pm. A southerly swell originating from hurricane kiko will likely bring strong rip currents at times at area beaches between Tuesday and Wednesday. A high rip current risk is likely for this period. There is a 50 percent chance that elevated surf between 3 and 5 feet will occur on Tuesday and Tuesday night mainly along the los angeles county coast.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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. |
