-- Notice published by the National Oceanic and Atmospheric Administration, NOAA (25 June 2025), announcing that after 40 years, on 5 days' notice, the U.S. Department of Defense will no longer provide satellite weather data, leaving hurricane forecasters without crucial information about storms as peak hurricane season arrives in the Atlantic.  The termination has been delayed by 1 month after an outcry from scientists and forecasters, NPR "Defense Department will stop providing crucial satellite weather data" (1 July 2025)
