This US Air Force handout photo released September 2, 2016 shows an empty aircraft ramp at Tyndall Air Force Base, Florida on September 1, 2016. Tyndall AFB sheltered all aircraft in preparation for Tropical Storm Hermine, one of the only times there have been no F-22 Raptors on the ramp since their arrival. US weather officials warned Tropical Storm Hermine posed "life-threatening" danger on Friday despite weakening as it moves across Florida and up the East Coast. / AFP PHOTO / US AIR FORCE / Airman 1st Class Cody R.MILLER / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / US AIR FORCE/Airman 1st Class Cody R.
