As of October 6, 2013 Sunday, Bayan Patrollers in Barangay May, Cebu City sent these videos of a tornado at about 4:30pm. The first video shot by Macky Malinao shows the twister as it formed out in the sea. Malinao said the twister was active for 4 to 7 minutes, died down, and was active again for about 6 to 7 minutes.
The same tornado was captured in the second video by Martmien Satur from another angle and sent by Bayan Patroller King Mungas.
Commentators on YouTube says that the formed Tornado was a waterspout , and absolutely they were right and the common term for that is “Tornadic waterspouts”, also accurately referred to as “tornadoes over water”, and formed from mesocyclonic action in a manner essentially identical to traditional land-based tornadoes in connection with severe thunderstorms, but simply occurring over water.
A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water, connected to a cumuli form cloud. In the common form, it is a non-supercell tornado over water. While it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones do occur. Waterspouts do not suck up water, the water seen in the main funnel cloud is actually water droplets formed by condensation.
Waterspouts have long been recognized as serious marine hazards. Stronger waterspouts can be dangerous, posing threats to water craft, air craft and swimmers. It is recommended to keep a considerable distance from these phenomena, and to always be on alert through weather reports.
