NASA images show power outages and recovery after Hurricane Isaias in Florida

Nighttime satellite images showed lighting in affected areas approaching pre-storm conditions by October 14.

Hurricane Isaias knocked out power in parts of Florida’s Gulf Coast. NASA satellite imagery tracked the decline in nighttime lights and their return over several days.

Isaias became the first hurricane of the 2026 Atlantic season on October 8 as it moved toward the U.S. Gulf Coast. It brought heavy rain and flash flooding to parts of the Southeast, including Alabama and the Florida Panhandle. Winds toppled trees and damaged power lines.

The storm made landfall near Destin, Florida, on the evening of October 9 as a Category 2 hurricane, with maximum sustained winds of 105 miles (170 kilometers) per hour. Preliminary National Weather Service reports recorded a 117-mile-per-hour gust in Oriole Beach and a 102-mile-per-hour gust at Pensacola City Hall.

NASA Black Marble HD satellite images showed sharp declines in nighttime lights in parts of Pensacola and along the U.S. Route 98 corridor toward Destin. Lights remained visible at Pensacola International Airport, Pensacola Christian College and parts of downtown Pensacola.

NASA scientist Ranjay Shrestha said the areas where lights persisted could reflect backup power, differences in electrical infrastructure or places that retained electricity during the storm. The images alone cannot establish the reason.

Images from October 11 and 12 showed lights beginning to return in some affected areas. By October 14, lighting patterns looked similar to those before the storm. Black Marble data complement ground-based outage reports but do not replace them.

NASA’s Disasters Program, working with FEMA and the U.S. Geological Survey’s Coastal Storms Team, is supporting the Alabama Red Cross and the Alabama Emergency Management Agency’s response. The team will post maps and data products on its open-access mapping portal as more information becomes available.
