We had evacuated during hurricane irma to the bonaventure resort and spa in weston, florida. at appoximately 7:00 p.M. eastern time, we were notified of a tornado warning for our area, as we were going through a heavy outer band of the storm. i stepped onto our balcony to search the skies for threatening weather. looking to the north, i saw a lower cloud deck, approximately 500 feet and an upper cloud deck at approximately 2000 feet, both moving a slightly different speeds. winds were gusting over 60 mph at the time. then coming from behind a cloud, i noticed a black boomerang shaped object that was between the upper and lower cloud decks, moving in a straight line from south to north. it's speed seemed constant and not consistent with the speed of the clouds. at the time all local airports were closed, and hurricane hunter airplanes are not allowed to fly over populated areas during a storm, and it was much lower than any aircraft that would have been flying over. the was the first time i had ever seen something i could not explain in the skies in the light of day, i had occasionally seen strange lights in the skies in my life, but this was during the light of the evening and so clear that it gave me a chill. i continued to watch the object for approximately 45 seconds to a minute when it was overcome by moving clouds and i lost sight of it.
