Here is what will be denied to NOAA, now and going forward
Defense Department data also allow hurricane forecasters to see
hurricanes as they form, and monitor them in real-time.
For example, hurricane experts can see where the center of a
newly formed storm is, which allows them to figure out as
early as possible what direction it is likely to go, and whether
the storm might hit land. That's important for people in harm's way,
who need as much time as possible to decide whether to evacuate,
and to prepare their homes for wind and water.
The public paid for this data. Deliberately siloing the data to insure it can't save American lives wouldn't just be theft, it would be an act indistinguishable from evil.
