Coastal Flood Advisory in Force August 8 for San Francisco and Monterey Bay Shorelines
A Coastal Flood Advisory covering five zones along the San Francisco Bay Area and Monterey Bay coastlines is in force on Saturday, August 8, 2026 — the local date carried on the advisory record (2026-08-08) issued by the National Weather Service San Francisco CA. The record is published in the National Weather Service raw text product archive at tgftp.nws.noaa.gov.
The advisory record sets the alert level at advisory. It runs from 5 PM Friday, August 7, 2026, through 2 AM PDT Thursday, August 13, 2026; the record's own timing line reads: "From 5 PM Friday to 2 AM PDT Thursday."
According to the advisory record, up to 1.6 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways. The locations named are bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay.
The five zones listed on the record are San Francisco, North Bay Interior Valleys, San Francisco Bay Shoreline, Northern Monterey Bay, and Southern Monterey Bay and Big Sur Coast.
The record describes the expected impacts as flooding of lots, parks, and roads with only isolated road closures expected.
On precautions, the advisory record states that high tides may result in flooding along coastal trails, cut off access to some low-lying coastal areas and beaches, and bring water and waves farther up the beach than typical. It advises that if travel is required, drivers should allow extra time as some roads may be closed, and that people should not drive, bike, or walk around barricades or through water of unknown depth. It also directs residents to take the necessary actions to protect flood-prone property.

Revision history

Added the record's local date (August 8, 2026, printed also as 2026-08-08) to the headline, dek and opening sentence so the event is dated rather than identified only by weekday. Retained the full start and end datestamps (5 PM Friday, August 7, 2026 to 2 AM PDT Thursday, August 13, 2026) and quoted the record's timing line verbatim. Printed the inundation figure exactly as given (1.6 ft) in both dek and body. Named the source record explicitly as the National Weather Service San Francisco CA advisory record published in the NWS raw text product archive, and added the record's alert level (advisory). Restored the omitted precaution about taking necessary actions to protect flood-prone property in full and kept all five zone names.

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.
