The Eye of Maria north of Hispaniola

September 21st, 2017 |

GOES-16 data posted on this page are preliminary, non-operational and are undergoing testing

Hurricane Maria presented a very interesting eye structure during the course of the day on 21 September 2017, as shown in the mp4 animation above (also available as a YouTube video).  The animation shows 10.3 µm imagery every 2 minutes from 0849 UTC through 2122 UTC on 21 September 2017.

Pete Pokrandt, at the University of Wisconsin Atmospheric and Oceanic Sciences Department, created a similar animation using the 0.64 µm Visible channel on GOES-16.

30-second interval (using overlapping 1-minute interval Mesoscale Sector) GOES-16 Visible (0.64 µm) and Infrared Window (10.3 µm) images covering the 6-hour period from 1031-1631 UTC are shown below. During this time, Maria re-intensified to a Category 3 hurricane, with the eye centered just off the northeastern coast of the Dominican Republic.

Suomi NPP Overflew Puerto Rico at ~0555 UTC on 21 September, and the Day Night Band Visible Imagery (0.7 µm), above (from Real Earth, direct link here), shows city lights from San Juan and Ponce on the northeast and southwest shores, respectively, shining through relatively thick clouds to the southeast of the eye of the storm.

Annotated Imagery from Suomi NPP (VIIRS Day Night Band Visible (0.7 µm) Imagery and Infrared (11.45 µm) courtesy of William Straka) are shown below.
