Choi-Wan tracks over open water — no coast is in the outlook. Along its path, our forecast reads:

This is the West Pacific · 21°N–45°N, 144°E–159°E. Choi-Wan’s forecast track is the dotted spine — the labelled dots mark its position each day. Every cell is shaded by how many hours it spends inside Choi-Wan’s gale-force (≥34 kt · 39 mph) wind across the whole forecast, the damaging core counted double.

Read it two ways at once. Colour is the total — the hours of gale-force wind a place piles up. A slow storm writes its danger in duration, not in any single gust, so the longer the wind sits over a place, the deeper its colour. Opacity is uniform here — this basin publishes no wind-speed-probability field, so the map claims no confidence it has not earned.
