High Surf Advisory Extended Through Tuesday for Los Angeles County Coast
The National Weather Service has extended its high surf advisory and coastal flood advisory for portions of the Los Angeles County coast, with the advisories now in effect until 11 p.m. Tuesday, September 8, according to mynewsla.com. The advisories, which began at 6 a.m. Friday, September 5, were previously set to expire earlier; the office has pushed the end time back, extending the warning window.
The advisories cover portions of the Los Angeles County coast, including Malibu, Long Beach's Alamitos Peninsula, and Avalon. A large southerly swell generated by the hurricane is expected to affect Southern California beaches from Friday through Tuesday, with the swell likely peaking Sunday and Monday, mynewsla.com reported.
Elevated surf is expected at south-facing beaches, along with very strong rip currents. Evening high tides of around 7 feet are expected during portions of the event, increasing the potential for moderate flooding in low-lying coastal areas and significant beach erosion, according to mynewsla.com.

How we work
This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.
Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.
Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.
None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
