I agree the buoys are probably broken, however, I was just pointing out that a tornado that forms over water is called a waterspout. FYI... here are some facts concerning hurricanes and tornados.

Tropical Cyclone Spawned Tornadoes Facts

10% of deaths in the United States are associated with hurricanes are a result of tornadoes.
Most tornadoes occur within 24 hours after hurricane landfall. The exception is when there is interaction with a cold front after landfall. Then more tornadoes will occur two or three days after landfall, well inland.
Most tornadoes occur within 150 miles of the coastline.
More tornadoes occur during the morning and afternoon rather than evening or night due to the need for a tornado to have a heat source.
The Gulf of Mexico hurricanes produce more tornadoes than Atlantic storms.
The majority of tornadoes occur within 30 miles of the center of the cyclone, but there is a secondary maximum further away in the outer rain bands (100-150 miles away from the center).
Tornado winds can reach up to 300 mph at a forward speed of 60 mph and are usually 100-300 yards wide.

Just one more reason to evacuate if you are in the path.
