5-minute CONUS Sector GOES-19 (GOES-East) Microphysics RGB images with an overlay of Next Generation Fire System (NGFS) Fire Detection polygons (above) showed the thermal signature of a fire that resulted from an explosion at the Valero oil refinery in Port Arthur, Texas late in the day on 23 March 2026. The initial NGFS thermal signature... Read More
5-minute CONUS Sector GOES-18 (GOES-West) Infrared images viewed using RealEarth (above) displayed deep convection (with intermittent GLM-indicated lightning activity) that moved across the Hawaiian island of O’ahu on 20 March 2026 — producing heavy rainfall and flash flooding.The first Flash Flood Warning for O’ahu on that day was issued at 0857 UTC,...
