This is the West Pacific · 25°N–39°N, 128°E–150°E. Surigae’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 Surigae’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.
