On 15 July Hurricane Fernanda became the first Category 4 tropical cyclone of the 2017 Northern Hemisphere season. GOES-16 “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed the development of a well-defined eye during the period of rapid intensification. As the National Hurricane Center mentioned, it was unusual to have a hurricane of this intensity at such a low latitude in the Eastern North Pacific Basin.

Fernanda fluctuated between Category 3 and Category 4 intensity during the 15-17 July period (ADT | SATCON) as it passed over the warm waters of the East Pacific Ocean (Sea Surface Temperature and Ocean Heat Content) — and trochoidal oscillations in the northwestward motion of the eye could be seen in GOES-16 Infrared Window (10.3 µm) imagery (below).
