“NOAA’s aerial imagery aids safe navigation and captures damage to coastal areas caused by a storm,” the agency said.
The imagery covers areas surrounding Mobile, Ala., and Pensacola, Fla., which show damage to marinas and the Pensacola Bay Bridge.
Other photos show sections of the Pensacola Bay Bridge that are now missing after being knocked into the bay by a barge that became loose.
“Aerial imagery is a crucial tool to determine the extent of the damage inflicted by flooding, and to compare baseline coastal areas to assess the damage to major ports and waterways, coastlines, critical infrastructure, and coastal communities,” NOAA said. “This imagery provides a cost-effective way to better understand the damage sustained to both property and the environment.”
Major beach erosion can also be seen in other images from barrier islands in the area.
Large amounts of sand were also pushed into areas with beach homes from Sally’s storm surge.
In all, Sally’s damage is expected to cost upward of $2 billion, Reuters reported.
Sally made landfall as a Category 2 storm near Gulf Shores, Ala., after strengthening as it approached the coast.
The storm was blamed for two deaths in the region.
At one point, Sally was one of five active tropical cyclones whirling in the Atlantic basin.
Forecasters said at the time it was only the second time in history that so many storms had existed in the Atlantic simultaneously.
