A satellite program that has historically been a key source of weather forecasting data will be discontinued by July 31, as the United States enters peak hurricane season, according to the already resource-strapped National Oceanic and Atmospheric Administration.

The program was initially supposed to be cut off June 30 to "mitigate a significant cybersecurity risk," NOAA said in an announcement. The agency now says it's postponing that until July 31. Peak hurricane season is usually from mid-August to mid-October.
