Crossing the International Dateline, Hurricane Nolo becomes Typhoon Nolo
10-minute Full Disk scan GOES-18 (GOES-West) Infrared Window images (above) showed Hurricane Nolo as it was intensifying from a Category 1 to a Category 2 storm while approaching the International Dateline (180 degrees longitude) on 04 October 2026. Once the tropical cyclone crossed the International Dateline, its ocean-basin-specific designation changed from Hurricane Nolo to Typhoon Nolo. The diameter of Nolo’s eye increased as it approached the Dateline — and the coldest cloud-top infrared brightness temperatures associated with deep convection were around -77C.
An overlay of GOES-18 GLM Flash Extent Density (below) revealed intermittent lightning activity with Nolo — which was less frequent within the eyewall region.
Illumination from the Moon (in its Waning Crescent phase, at 37% of Full) provided a nighttime visible image of compact Hurricane Nolo using the VIIRS Day/Night Band on NOAA-20 (below).
A Synthetic Aperture Radar (SAR) image from Canada’s RCM-2 satellite (below) sensed surface wind speeds as high as 121.35 knots in the NW quadrant of Hurricane Nolo.
