Tropical Storm Nolo

Tropical Storm Nolo is packing 55-kt (65-mph) winds, moving WNW at 5 kt (6 mph). Expected to stay over open water.

At 200 AM HST (1200 UTC), the center of Tropical Storm Nolo was located near latitude 22.2 North, longitude 164.8 West. Nolo is moving toward the west near 6 mph (9 km/h) across the Papahanaumokuakea Marine National Monument. A generally westward motion is expected through the latter part of the week. Maximum sustained winds have decreased to near 65 mph (100 km/h) with higher gusts. Further weakening is forecast over the next day or so, followed by some re-intensification during the latter part of this week. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 991 mb (29.27 inches).— National Hurricane Center · public advisory 39

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

This is the East Pacific · 20°N–30°N, 176°W–197°E. 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.
