Florida and Louisiana have their share of natural disasters like hurricanes, and floods. Being so close to the ocean with such dynamic weather changes can also lead to another catastrophic event: a waterspout. A waterspout’s potential for damage depends on the type of waterspout it is.
Waterspouts are tornado-like whirlwinds of water mist and air that usually start over the ocean and can move over land.
According to the National Oceanic Atmospheric Administration (NOAA), a waterspout is a “ whirling column of air and water mist .” They essentially look like a tornado over water, but certain waterspouts can move over land for some time. Waterspouts that move onto land can be dangerous and cause damage to both property and people.
Waterspouts that hit land can be perilous because of their speed and size. While the average waterspout is 165 feet in diameter and lasts anywhere between two and 20 minutes, massive ones can exceed 330 feet in diameter and may last up to an hour. Wind speeds may exceed 50 miles per hour.
There are two types of waterspouts: fair weather and tornadic.
How a waterspout forms depends on the type of waterspout it is.
A fair weather waterspout occurs over open water when cool air sweeps across the surface and pulls the water up.
Tornadic waterspouts are different in that they happen during thunderstorm conditions – some even start as tornadoes on land and move over water. Additionally, tornadic waterspouts are more likely to develop in the sky and reach down.
The five stages of a waterspout are:
The key component of any waterspout is the focused cold air cycling over the warm surface water. Once the conditions are met, a waterspout could develop.
With speeds exceeding 50 miles per hour, homeowners could see damage from a waterspout, particularly if it picks up debris and sends it into their home. Luckily, most homeowners insurance covers waterspouts as windstorm damage. However, if a waterspout happens because of hurricane conditions, homeowners should note that policies only cover damage caused by wind. Storm surge from a hurricane is usually covered by flood insurance.
