no official probability field for this basin — opacity uniform

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.
