A plot of the Advanced Dvorak Technique intensity estimate for Cyclone Emeraude in the Indian Ocean (above) shows that the storm rapidly intensified to Category 4 intensity on 17 March 2016.

Himawari-8 AHI Visible (0.64 µm) and Infrared Window (10.4 µm) images (below; also available as a large 31-Mbyte animated GIF) revealed the formation of a well-defined eye during the day.

Nighttime images of Suomi NPP VIIRS Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) data at 1859 UTC (below, courtesy of William Straka, SSEC) showed the ragged appearance of the eye at that time, with an isolated convective burst that had developed well west of the eye.
