Next Generation Fire System (NGFS) -- CIMSS

GOES-East switch from GOES-16 to GOES-19 has been delayed to ‘no earlier than’ Monday, April 7 due to declaration of a critical weather day on Friday, April 4. There may be a short disruption in the NGFS detections or imagery during the transition to the new satellite. More information. Delay information.
