1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed Category 1 Hurricane Hanna making landfall along the South Coast of Texas at 2200 UTC on 25 July 2020. The coldest cloud-top infrared brightness temperature was -88.6ºC at 1633 UTC. Winds gusted to 76 mph at Buoy 42020, and at 18 UTC a ship about 30 miles off the Texas coast reported blowing spray.

GOES-16 GLM Flash Extent Density (below) showed little to no lightning activity within the immediate eyewall region of Hurricane Hanna during the 9 hours leading up to landfall; however, lighting did increase somewhat after the 22 UTC landfall.
