Coastal Flood Advisory issued June 17 at 6:25AM PDT until June 18 at 5:00AM PDT by NWS San Francisco CA

No next occurrence is being forecast right now — this pattern has gone quiet and needs to keep recurring before we forecast it again.

Why: it has occurred on 6 days — every day we've been watching, usually around 01:29 UTC.

Defaxon forecasts when a recurring event is likely to happen again — its rhythm — not the outcome. For a sports fixture that means we flag that the match recurs, not who wins; for a flight, that the route runs, not whether it’s on time. It’s probabilistic early-warning, never prophecy, and it sharpens as the archive grows.

How accurate have we been?

Of 2 forecasts we committed to before the fact, 2 came true — an earned 100% hit rate, measured against reality and never asserted.

Upcoming & past forecasts

Each is a window we forecast ahead of time; it resolves to ✓ if the event recurred in that window, ✗ if it didn’t.
