Hurricane Nolo

Hurricane — Category 1 Nolo is packing 80-kt (90-mph) winds, moving W at 4 kt (5 mph). Expected to stay over open water.

At 1100 AM HST (2100 UTC), the center of Hurricane Nolo was located near latitude 16.7 North, longitude 156.0 West. Nolo is moving toward the west near 5 mph (7 km/h) and is expected to accelerate westward through the weekend. Then, a turn toward the northwest and north-northwest is forecast on Monday and Tuesday. On the forecast track, the center of Nolo will remain well south and southwest of the main Hawaiian Islands. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Nolo is predicted to strengthen into a major hurricane on Sunday and peak in intensity by early Monday. Thereafter, steady weakening is expected. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The minimum central pressure based on aircraft data is 977 mb (28.85 inches).— National Hurricane Center · public advisory 25

This is the East Pacific · 15°N–27°N, 173°W–154°W. Nolo’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 Nolo’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.
