A period of high-based convection to the east and northeast of Hawaii was producing occasional lighting on 3 June 2024, as shown in the animation above. LightningCast Probabilities plotted show values around 50%, and lightning is occurring. Note that the Flash Extent Density colorbar has been modified to have a... Read More
5-minute PACUS Sector GOES-18 (GOES-West) Shortwave Infrared (3.9 µm) images (above) showed the thermal anomaly (heat signature) following the onset of an eruption of Kilauea on the Big Island of Hawai`i — which began around 1030 UTC on 03 June 2024. The peak 3.9 µm brightness temperature sensed at the eruption site was... Read More
5-minute CONUS sector GOES-18 (GOES-West) Day Fire RGB, Shortwave Infrared (3.9 µm), Fire Temperature RGB and “Red” Visible (0.64 µm) images with overlays of the Fire Power and Fire Mask derived product (2 components of the GOES Fire Detection and Characterization Algorithm FDCA) (above) displayed signatures of the Corral Fire, which started around 2126 UTC on 01 June 2024 in...

1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images (above) displayed areas of convection that moved across American Samoa on 01 June 2024 (1-minute imagery was requested by NWS Pago Pago to monitor the approach of thunderstorms, since they had issued a Flood Watch for the islands — and they lack radar coverage). Although there was a... Read More
