TIROS-1 showed a typhoon near Australia, cloud patterns over the US, and allowed for the first time meteorologists to view storms from space and track their motion.
Previously, storms over the ocean might go entirely unnoticed except for chance reports by ships, and powerful storms could come as a total surprise when they reached land, resulting in far higher deaths and injuries than today.
In spite of the terrible damage from Hurricane Sandy, we should be thankful for the space program which developed life-saving weather satellites, and allowed early warning of Sandy's path and destructive force. There would have been far greater loss of life in previous decades. As an example, thousands died in the 1900 Galveston Hurricane as evacuation in advance was not possible as it would be today.

Today's weather satellites provide far greater resolution and data than the first, and can monitor tsunamis and even receive broadcasts from emergency beacons. Astronauts on the International Space Station frequently photograph storms and other phenomena such as aurora.
Completing the picture are weather apps for smart phones as well as emergency alert apps. Anyone care to forecast what's next on the horizon?
