Hurricane — Category 3 Polo is packing 100-kt (115-mph) winds, moving NNE at 9 kt (10 mph). Skirts the coast Tue, then moves inland over the coast Tue as a weakening tropical storm.

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

This is the East Pacific · 22°N–32°N, 116°W–107°W. Polo’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 Polo’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 confidence — solid where the official probability of that wind is high, faint where it is only a chance. So a deep, solid cell is a place the wind will work for a long time and likely will; a pale, faint one is a brief, uncertain brush at the edge of the cone.
