It is impressive to look at but I understand that waterspouts that survive to turn into destructive tornados on land are fairly rare. The last good one that I can recall to blitz through Ft. Lauderdale happened in the 1970's. There may have been others but they don't appear to be that common. So, I wouldn't lose sleep over this threat. Interesting clips though.

Bringing this old thread back, with this good sized waterspout off the Juno Pier last evening at about 7 pm. Here is a video:


"This is a video I took of a waterspout off of Jupiter, FL on June 24, 2012 at approximately 6:45 pm using my iPhone. The storms that spawned the waterspout are affiliated with tropical storm Debby."


Here are some still shots including a capture from the above video from WPTV,

The waterspout was located below that red bow hook that shows up off Jupiter/Juno below:

Checkout the post above this one for images on the massive waterspout sighted off Juno Beach last evening.

As visible as waterspouts are, kiters still fall victim to them at times. In the case of "fair weather" waterspouts the sun and partial cloudiness might take them in. A kiter was killed by one of these in Italy with another coming close to it.


A waterspout in Cerveteri, Italy on 6.20.09. Three kiters were lofted almost simultaneously with one fataly striking a building, another hitting a car and the third was able to emergency depower while on the beach.

"Real bad news, my sympathy goes out to the lost kiters family and friends. Best wishes for the full recovery of the other rider who was lofted at the same time. It looks like a third kiter was lofted but didn't suffer serious injury.

Internet translation:
Cerveteri, tornado sweeps surfers:
33enne building on crash dies

ROME (June 20) - They were doing kite-surf near the center of Ocean Surf Margherite the way to Campo di Mare (Cerveteri) when, at about 13.30, he caught a tornado making him take a flight of several meters . A man of 33 years originally from Cerveteri, living in Treviso and kitesurf instructor, was banged on the roof of a building of the promenade of Via delle Margherite and fall to the ground, ended against a railing of iron shot on the dying.

Another surfer, thirty, is over against the car passavno currently showing several fractures for which he has been admitted to the Gemelli Polyclinic, where he was transported to eliambulanza. Despite the prognosis confidential, is not in danger of life. More lucky the third, fallen on a stretch of beach: if you got with no serious injuries.

The swimmers who have witnessed the incident told the fire brigade intervened to have seen a whirlwind of air and the surfer, then dead, then a flight of 30-40 meters.

From: http://www.ilmeteo.it/clienti/ilmessaggero/homebox.html

and a TV report, http://tg24.sky.it/tg24/cronaca/2009..._un_morto.html

Looking at the satellite loop, it looks like a frontal boundary passed over the area of Italy around midday."

We have also had a kiter permanently paralyzed by yet another waterspout. All were blown horizontally with substantial force at speed. Waterspouts have sunk boats and played havoc with things at sea since we've been out there. I would avoid them like the plague.


Waterspout wind field. Checkout the horizontal outflow component and the undefined vertical component by the shaft. Winds plenty strong enough to mess up a kiter.

There are fair weather waterspouts, such as frequent the Florida Keys and Great Lakes. These generate winds on the order of less than 60 mph to around 100 mph, perhaps more. These are associated with cummulous clouds. Then there are tornadic waterspouts connected to supercell cummulonimbus storm clouds. The super cell can throw out lethal winds all by itself without any input from the waterspout. This is a far more common scenario where kiters are concerned. Tornadic waterspouts can develop into as high as F5 tornados on land although rarely. An F1 twister is plenty enough to kill you though if you have a kite up, regardless of kite orientation.

Here is a video of a waterspout that went ashore in Australia and turned into a tornado in short order. Checkout the debris field, anyone up for flying a kite through this?

A fair weather waterspout came ashore opposite Bahia Mar yesterday in Ft. Lauderdale, FL. It threw an bounce house containing four young kids what appears to be 30 ft. + into the air, over the pedestrian bridge and apparently into A1A perhaps 300 ft. downwind. Three were released from the hospital while the third, a young girls is still at Broward General. I wish her all speed in healing and going home soon.

The waterspout, (actually dust devil or tornado at that point?) broke a light pole (aluminum?) and a steel basketball standard. Waterspouts are common in the warmer months in South Florida. Sometimes they can quietly "sneak" up on you if you aren't looking in that direction. It looks like many at the beach and park were unaware it was moving ashore close to them.

I don't think it is practical to configure a bounce house for such weather extremes. About all you can do is to stay aware, particularly this time of year. I recall at least one other bounce house being picked up by a dust devil or twister in recent years. Funnel clouds and waterspouts have killed and paralyzed some kiters in Europe. If you are out, particularly this time of year kiting, you need to stay aware and look for things like this.

As developed and controlled as our world may seem, weather phenomena still occur which are beyond our ability to oppose or control. Lightening, hurricanes, drought, blizzards, bursts and on, it is a long list. We need to avoid these hazards and otherwise manage ourselves the best that we can to try to avoid harm. Stay aware, use good sense and try to avoid problems.



A fair weather waterspout is more of a subtle threat and about the only way to try to reduce the odds of problems is to stay aware. If you see one, seek cover immediately in a good safe, shelter or if in a boat proceed at best speed 90 degrees from its direction of travel.

Signs to look for, black bases on flat cumulous clouds (cloud streets), funnel droops or "pointy" or ragged features along cloud base, dark spots on the water, rotating water masses at cloud base or on the water. You can actually see these funnel clouds try to develop, fail, merge, vanish, reappear a times.


A long low, flat cumulus cloud which generated a clear weather waterspout severely hurting some kiters in Italy.

Waterspouts often dissipate rapidly once on land, but not always. Sometimes they turn into tornados. There was one which did a lot of damage to several houses in the Harbor Beach area just to the southeast in the 1970's. There are tornadic waterspouts associated with severe thunderstorm clouds with greater potential for harm. Usually, the clouds they are associated with are far more threatening in appearance than the fair weather waterspouts.




A funnel cloud forms in Italy but the kiter seem unaware or unconcerned. The accidents happened shortly after this point.

Shea Gibson with WeatherFlow/iKitesurf just prepared a good article on what causes morning waterspouts to develop off South Carolina.
Some of the same principles apply to funnel cloud and waterspout formation off Florida as well.
