If you’ve never heard of a waterspout before, don’t worry—you’re not alone! Most people probably don’t think about tornadoes over water, but they’re very real, and when they hit, they can be devastating. Case in point: the recent freak incident off the coast of Sicily, when a waterspout tore through a luxury yacht and sank it. Let’s dive into what happened and why we might start seeing more of these unusual storms.

What exactly is a waterspout?
Think of a waterspout as a tornado over water. It’s a rotating column of air and mist, swirling above the surface at crazy speeds—sometimes reaching up to 200 kmph. While waterspouts can be smaller and less powerful than tornadoes over land, they are still serious business. Boats caught in their path don’t stand a chance.
The storm that hit off Sicily was a perfect example. A yacht called Bayesian was sailing along in what was probably expected to be a beautiful Mediterranean voyage. But early in the morning, disaster struck: a waterspout suddenly formed and the yacht flipped, sinking in the blink of an eye. At the time of writing, several bodies have been recovered and some are still missing.

Why are they so dangerous?
Well, for one thing, they’re sneaky. They form quickly, often without much warning, and if you’re out at sea, there’s nowhere to go. On top of that, they pack winds strong enough to rip apart boats or toss debris around like confetti at a party. In the case of the Bayesian, by the time rescuers reached the scene, all they found was debris floating on the water. It’s also worth noting that the seas around Italy have been warmer than usual lately—by a few degrees, in fact. This extra warmth gives these storms more energy, making them stronger and more unpredictable.

Is climate change to blame?
This isn’t just a freak occurrence. Waterspouts are happening more often, and the experts think climate change is to blame. As global temperatures rise, the air holds more moisture, which can lead to more intense storms and, in turn, more waterspouts.
Italy and the surrounding Mediterranean region, in particular, are starting to see more of these extreme weather events. Last year, 15 waterspouts were spotted in a single day across Italy, France, and Spain! That’s not normal, and it’s a big sign that these storms are becoming a regular part of life in the area.
Climatologists believe that as the Mediterranean continues to heat up, we’re going to be seeing more waterspouts, storms, and all sorts of other wild weather (Vega et al. 2022). It’s not just about hotter summers anymore; these changes have real consequences, as the tragic sinking of the Bayesian shows.
What next?
This story isn’t just a warning for boaters—it’s a wake-up call for all of us. As climate change reshapes the weather patterns we’ve long relied on, events like this could become more frequent. So whether you’re a sailor or someone who loves a good beach day, it’s something we all need to pay attention to.
In the meantime, authorities are still searching for the missing from the Bayesian. It’s an unfortunate reminder that nature can turn deadly in an instant. The hope is that with more awareness and action on climate change, we can help prevent more tragedies like this from happening in the future.
