Power outages across Gulf Coast

  • Published
The aftermath of Hurricane Katrina was captured by an Air Force meteorological satellite from the Air Force Weather agency here as it flew over the southeastern United States.

The image taken Aug. 30 shows the widespread power outages across the Gulf Coast after Hurricane Katrina ravaged the area. In a file image, taken Sept. 17, 2003, city lights are clearly visible.

The defense satellites have a low-light sensor on board that is sensitive enough to see city lights from space, a capability that is unique to Air Force weather satellites. The satellite provides multispectral images that use both infrared and visual satellite imagery to produce a color composite that reveals clouds and lights.

The infrared portion is in blue, showing clouds, and the visible portion is in yellow, showing city lights and fires.
