Help Center ยท The signals in depth

Weather and hazard alerts

National Weather Service alerts for the island. Environmental context alongside the human signals, never a crime measure.

Weather brings in National Weather Service alerts for the island, flood, wind, surf, and similar, as context alongside the human signals. It is environmental, never a crime measure.

The Oahu weather and hazard page: National Weather Service alerts for the island by type and time.
Weather is a context layer: island hazard alerts shown next to the human signals, so a spike or a quiet stretch can be read in context.

What it is

It counts NWS alerts issued for the island (flood advisories, high-surf and high-wind warnings, and the like), by type and time.

What it can tell you

The environmental backdrop for a period. A stretch of hazard alerts can help explain why other signals moved, or simply give an honest picture of what the island was dealing with.

What it cannot tell you

It is not a crime or safety signal and is never combined with one. It is context, shown side by side, never a forecast or a verdict.
