Weak northeast winds are expected to develop this weekend, bringing drier conditions and warmer temperatures to the region that will persist into next week. There is another chance of rain late this coming week into next weekend.
(Fri-Mon), 23/843 PM.
***UPDATE***
A few thunderstorms moved over portions of eastern LA County from the north late this afternoon into the early evening, with some heavy downpours, lightning and gusty winds.
That activity has ended and now expect a clearing and drying trend as gradients shift to weakly offshore. Expect the strongest northeast flow to occur on Saturday, then weakening into Sunday. These weak offshore winds will most likely peak below Advisory levels, with breezes up to around 30 mph in the LA and Ventura Valleys, and 40-45 mph in the mountains. A much warmer day is expected Saturday, with highs up anywhere from 8 to 14 degrees in most locations. Highs in the 70s to low 80s are expected, with an additional few degrees of warming on Sunday. After that, little change in temperatures expected Tuesday into Wednesday. Weak offshore gradients will continue through this time.
(Tue-Fri), 23/129 PM.
A slow cooling trend is expected to begin around next Tuesday as an upper level low drops out of the Pac NW. This will begin the turn back towards onshore flow and in turn slowly cooling temperatures through the end of the week. It still looks favorable for rain to return to southern California late next week with the most likely day being next Saturday (Halloween) or Sunday.

Gusty west to northwest Small Craft Advisory (SCA) winds will impact most of the waters through tonight, including the western half of the Santa Barbara Channel. Seas near 10 feet will continue through late tonight across portions of the outer waters. Otherwise, relatively quiet conditions are expected through the weekend except for localized SCA northeast wind gusts nearshore from Point Mugu through the Malibu coast in the morning hours Saturday & Sunday.There is a 30% chance of SCA NE wind gusts nearshore from Point Mugu to Malibu late tonight through Saturday morning.
Northwest winds will increase next week, with around a 50% chance of SCA level winds Monday through at least mid-week.
23/847 PM.
Very high tides between 7.5 and at least 8.0 feet (roughly 1.1-1.5 feet above astronomical predictions) are expected during the morning hours of Sunday- Thursday from Los Angeles (highest tides) north to the Central Coast. Due to the very high tides, moderate coastal flooding impacts can be expected at any low lying beach areas, not just south facing beaches as has been the case the last couple of months.
While we generally aren't seeing much in the way of any significant swells during this period, there is a small potential for a slightly larger, long period swell from the south Wednesday-Thursday that could create enough energy to produce some more impactful coastal flooding.
Coastal Flood Advisories are in effect Sunday-Thursday. There is a low potential for targeted Coastal Flooding Warnings if a larger swell develops and produces elevated surf on top of the very high tides.
Potential Impacts: -Minor to moderate flooding of sea water is likely over vulnerable low-lying coastal areas including over beach parking lots, bike paths, normally sandy beaches, and harbor walkways. -Moderate to significant beach erosion is likely. -Isolated damage of structures due to sea water inundation is possible.
Ca, Coastal Flood Advisory in effect from 5 AM Sunday to 1 PM PDT Thursday for zones 340-346-349-350-354-362-366. (See LAXCFWLOX). PZ, Small Craft Advisory in effect until 3 AM PDT Saturday for zones 650-670-673-676. (See LAXMWWLOX).
