1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed Hurricane Ian as it made landfall as a Category 1 storm near Georgetown, South Carolina at 1805 UTC on 30 September 2022 — producing wind gusts as high as 92 mph and rainfall totals exceeding 5 inches. The low-level circulation center was mostly obscured by... Read More

Polar-Orbiting satellites flying over Florida viewed remarkable changes in water quality from before and after the passage of Hurricane Ian. Imagery from Suomi-NPP, for example, from 25 September and 30 September, toggled below (imagery derived from the VIIRS Today website), shows a large increase in turbidity in the Gulf (and over the Atlantic...

Overlapping 1-minute Mesoscale Domain Sectors provided 30-second interval GOES-16 (GOES-East) “Clean” Infrared Window (10.3 µm) and “Red” Visible (0.64 µm) images (above) during a 7-hour period that included the landfall of Hurricane Ian along the southwest coast of Florida at 1905 UTC (Visible | Infrared) on 28 September 2022. Moving across very warm water (where buoy... Read More

The toggle above compares eyewall sizes from 2004’s Hurricane Charley and 2022’s Hurricane Ian near landfall in/around Fort Myer FL. Charley was a small cat-4 storm at landfall (link) with a 10-nm wide eye.. Hurricane-force winds with Charley extended only 15-25 miles out from the eye (link). In contrast, Ian... Read More
