Hurricane Matthew moved through the Bahamas overnight, slowly organizing and strengthening to Category 4 intensity after its interaction with the high terrain of the Greater Antilles (Note that Day/Night Band Imagery from overnight on 6 October — from this Blog Post — shows that city lights are back on in Port-au-Prince Haiti as recovery proceeds in that country). The three images above show the evolution of the storm from 0345 UTC to 1145 UTC on 6 October. A warm eye is present, but it is not a cloud-free eye.

The GOES-13 satellite continued to be in Rapid Scan Operations (RSO) mode, providing images as frequently as every 5-7 minutes. An animation of Infrared Window (10.7 µm) imagery is shown below (MP4 | animated GIF). Nassau, Bahamas (station identifier MYNN) experienced a wind gust of 74 knots at 13 UTC.

A higher-resolution view of the eye was provided by a Suomi NPP VIIRS Infrared Window (11.45 µm) image at 0645 UTC, below.

GOES-13 Visible Imagery from early in the morning on 6 October, below (MP4 | animated GIF), confirms the diagnosis of a cloudy eye. The center of the storm is moving northwestward between Andros Island to the west and New Providence Island to the east (Nassau, the capitol of the Bahamas, is on New Providence Island).
