This satellite animation is from NOAA’s GOES-16 (GOES East) satellite and runs from 13 May 2020 through 18 November 2020. The GOES East satellite recorded this imagery of the entire Atlantic basin from its operational location of 75.2 degrees west longitude. This allows us to show storms as they form off the coast of Africa and then enter the Atlantic. Video: NOAA
