5-minute CONUS Sector GOES-18 Clean Infrared Window (10.3 µm) images (above) showed elongated clusters of convection moving eastward and northeastward across Kauai and Oahu — with embedded thunderstorms that produced heavy rain and strong winds on those two islands (Local Storm Reports).

A corresponding animation of GOES-18 Infrared images with an overlay of GLM Flash Extent Density (below) displayed the abundant lightning activity associated with these thunderstorms.
