Hurricane Sally uprooted trees, flooded streets and cut power to hundreds of thousands of homes and businesses on Wednesday as it brought what the U.S. National Hurricane Center called "historic and catastrophic" flooding to the Alabama-Florida coast.

Sally, which made landfall early Wednesday near Gulf Shores, Alabama, as a Category 2 storm, was downgraded in the afternoon to a tropical storm as maximum sustained winds dropped to 70 mph (113 kph).

The storm is believed to have killed one person in Alabama.
