Hurricane Maria underwent rapid intensification on 18 September as it moved through very warm waters to the east of the Leeward Islands. The animation of GOES-16 “Clean Window” Infrared Imagery (10.3 \u00b5m), above, shows the rapid development of a warm concentric eye between 1640 and 1940 UTC. The toggle below, between 1600 UTC and 2000 UTC, testifies to a great increase in organization and strength.
