On Oct. 17, 2024, NOAA shared initial imagery from the GOES-19 lightning Mapper. The GOES-19 Geostationary Lightning Mapper (GLM) instrument, launched on June 25, 2024, is now continuously observing lightning over the Western Hemisphere. Recently, the GOES-19 GLM detected and monitored lightning activity in two extremely hazardous hurricanes – Helene and Milton. Lightning activity in the outer rainbands and eyewalls of these hurricanes was associated with rapid intensification. Frequent lightning outside the Hurricane Milton’s core was associated with intense rain bands that produced widespread flash flooding and tornadoes across Florida on Oct. 9, 2024.
GOES-19 is currently undergoing post-launch testing, which includes validation and calibration of its instruments, systems and data to prepare it for operations. NOAA plans for GOES-19 to replace GOES-16 as GOES East in April 2025.
Imagery and data from GOES-19 during the post-launch testing phase should be considered preliminary and non-operational.
