Satellites are critical for tracking storms, especially over the ocean. The deadliest natural disaster in the history of the United States was a hurricane that hit Galveston, Texas in September 1900. Communications were very different then so people had no advanced warning of the storm and over 8000 died.
This surprise weather scenario is unthinkable in the 21st century thanks to weather satellites. Meteorologists track possible hurricanes worldwide from the moment they start as small tropical depressions over warm ocean waters to the time when they dissipate days or weeks later. The same is true for thunderstorms, tornadoes, and blizzards.
