This cloud phenomenon seen over central Floria are known as Hole Punch Clouds or Fallstreak Holes. Such holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation particles. When ice crystals do form it will set off a domino effect, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud
