GOES-16 Visible Imagery, above, shows Tropical Storm Henri east of Florida and to the north of the Bahamas. Cirrus outflow is well-developed to the east and south, but the storm is sheared; the surface circulation is near the northwestern edge of the ongoing deep convection. Persistent northerly shear, as shown... Read More

GOES-16 “Cirrus” channel (1.38 µm) imagery, above, and visible (0.64 µm ), below, shows Tropical Storm Henri to the southeast of the island of Bermuda (at 32.3º N, 64.7º W) shortly after sunrise on 17 August 2021. The cirrus channel shows a compact region of convection and an expanding cirrus... Read More

1–minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed Tropical Storm Fred during the 8-hour period leading up to it making landfall along the panhandle of Florida around 1915 UTC on 16 August 2021. Multiple convective bursts developed near the storm center, with some exhibiting cloud-top infrared brightness temperatures of -80ºC or colder (violet pixels).... Read More

VIIRS Imagery from Suomi-NPP (the Day Night Band, at 0.7 µm and I05, at 11.5 µm, above, at 0704 UTC) and from NOAA-20 (the Day Night Band, at 0.7 µm and I05, at 11.5 µm, below, at 0754 UTC), show polar orbiting perspectives of Tropical Storm Fred. The Day Night Band shows little detail... Read More
