Cook Inlet current view
Cook Inlet has some of the strongest tidal currents in the world. This mode is designed to eventually show a simple SLACK / INCOMING / OUTGOING story with arrows on the map, tailored for set-netters, charter captains, kayak anglers, and photographers.

Concept: simple traffic-light currents
* Concept preview — this feature does not yet provide operational guidance. It is for demonstration purposes only.
The core of this mode is clarity, not raw numbers. Instead of forcing you to read complex current tables, Cook Inlet is divided into a handful of key reaches, each labeled with one of three states: SLACK, INCOMING, or OUTGOING.
- SLACK — current near zero; best for small craft crossings and slow drifts.
- INCOMING — flood toward Anchorage; often piles up waves against wind and bottom.
- OUTGOING — ebb toward the Gulf; can create strong standing waves, especially with north wind.
v1 is intentionally descriptive only; a future iteration will wire NOAA current stations and arrows on a focused map.
