Tropical Storm Nolo

Tropical Storm Nolo is packing 45-kt (50-mph) winds, moving WNW at 3 kt (3 mph). Expected to stay over open water.

At 200 AM HST (1200 UTC), the center of Tropical Storm Nolo was located near latitude 21.8 North, longitude 165.3 West. Nolo is moving toward the west-northwest near 3 mph (6 km/h). A turn to the west is forecast later today, before turning back to the west- northwest by late this weekend. Satellite wind data indicate that the maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Some gradual strengthening is forecast over the next couple of days while Nolo moves westward while remaining south of the Papahanaumokuakea Marine National Monument. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 994 mb (29.36 inches).— National Hurricane Center · public advisory 43

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, 177°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.
