Hurricane Irma at 1501 UTC just after the National Hurricane Center upgraded the intensity to 180 miles per hour.  This figure shows the ABI 10.3 micron infrared imagery with the corresponding GLM 8 km event density (to show spatial extent) and flash centroid points.  In this image 10 GLM flashes were observed.

This morning the National Hurricane Center upgraded hurricane Irma to a category 5 storm (7 AM Central, 1200 UTC).  By 10 AM Central (1500 UTC), the hurricane further intensified with maximum sustained winds of 180 miles per hour.  The linked mp4 movie covers just over 3 hours from ~1150 UTC through 1510 UTC.  The animation shows the ABI 10.3 micron infrared imagery (full disk, 15 minute resolution) and the GLM event density (to show spatial extent) and the flash centoid points.  This display is in AWIPS and uses the combined event density and flash centroid plot recommended by the Hazardous Weather Testbed (HWT) along with the color curve developed by NASA SPoRT and tested at HWT.  Of note is to watch the location of lightning in the storm as it varies between the outer bands and the eyewall.
