Usually the GOES-17 Mesoscale Domain Sector #2 is positioned over Alaska to provide 1-minute imagery — but on this day it was relocated to cover severe thunderstorms across New Mexico and Texas — so imagery over Alaska was only available at the 10-minute Full Disk scan interval.
In addition to the hail, these storms also produced heavy rainfall — especially at Fairbanks, with 0.65 inch falling in only 21 minutes.
