1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) and “Red” Visible (0.64 µm) images (above) showed Tropical Storm Eta as it began to move across the Florida Straits after 15 UTC on 08 November 2020. Deep convection began to develop across far southern Florida around 02 UTC on 09 November, just north of Eta’s broad circulation center — and the tropical storm made landfall in the Florida Keys at 0400 UTC. The strongest wind gusts were found to the north/northeast of the storm.

Maps of Sea Surface Temperature and Ocean Heat Content from the CIMSS Tropical Cyclones site (above) indicated that Eta was moving over warm water (SST around 28ºC, and a pocket of modest OHC) north of Cuba. GOES-16 Longwave Infrared (11.2 µm) images, with contours of 02 UTC deep-layer wind shear (below) showed that the hurricane was moving through an environment of moderate southwesterly shear, which limited intensification.
