Avoiding Hazardous Weather
A shelf cloud in the squall line goes to sea, taking a kite but no kiter with it, this time.
About 70% of kiter losses worldwide have occurred in high wind also including accidents in squalls in recent years. Over time riders have been lofted hundreds of feet, even 1700 ft. and 300 ft. high to hard collision, hundreds of feet into buildings, cars, trees, hitting sailboats and dying, being lofted and suffering permanent paralysis, dozens and dozens of them. Tragically most of these losses have been avoidable.
Why would someone risk this in an obvious and avoidable threat? Could it be lack of understanding and/or respect for the hazard? Despite this, kiters still go out intentionally in squalls and a percentage are harmed. It comes down to informed choice of course barring harm occurring to anyone else, still, it strikes me as a real bad idea from long personal experience. You can't guarantee others safety, including rescuers in such extreme events however or even the protection of our access. Our gear isn't designed for continuous riding in excessive winds and most don't even practice enough to realize what benefits our gear may offer in high wind emergencies despite that. A fools game to be frank looking over hundreds of accidents worldwide in the last thirteen years.
A shelf cloud rolls over Boca Raton, FL yesterday afternoon as the squall line rakes south down the state. Riders were out in some areas even as clouds looking like this approached? Bizarre, I believe we may be hard wired to try to avoid stuff like this from way back, yet some are still out there.
Folks that mess around with these systems may not understand what they are getting into or respect it. Can't help with the reasoning part too much but I can at least share some information for consideration.
1. Pre-frontal squall lines are common with up to several a week moving through. They occur worldwide to my knowledge in varying frequencies. They represent the battle ground between two separate weather masses. So it is logical that strong storms, convection can be present at these junctures in the form of violent squall lines at times.
2. Violent, powerful squall lines seem to becoming more common, perhaps due to climate change? Lots of tornados, bursts and related damage on the ground.
3. Squall lines are readily predictable* from:
- Marine and Hazard forecasts
- Color radar and satellite imagery
- Realtime wind reports (through wind spikes, violent & near 90 degree direction changes) up weather.
- Weather maps, with those frontal symbols and strong wind/storms warnings.
- To the naked eye at the beach although it is better to rely upon advanced warning provided by the above resources first and supplement with visual observations.
4. Squalls can move fast, over a mile a minute. In reduced visibility this means one could be on your in short minutes, not much time to react. They can be preceded by an advancing wind line, white water, blowing debris and obvious threatening clouds in some but not all cases. The temperature will drop, sometimes a lot, that is the air cascading down from 7 to 10 miles up smashing to earth in gust fronts. You could be comfortable before the arrival of the cold front and at risk of hypothermia if disabled after particularly in higher latitude storms in the cooler months.
5. Gust fronts may strike miles in advance of the squall cloud as can lightning. Squalls can also bring tornados, water spouts and microbursts. Microbursts can vomit winds to 170 mph over a couple of mile radius. Microbursts can be fairly common in such systems too as are tornados. These squalls can toss down hail too, some up to softball size. Getting whopped in the head with a good chunk of ice in free fall from miles up could take you out nicely, particularly with all that water to drown in.
6. Squalls may kill the wind entirely, boost it to hazardous levels or leave it unchanged. Sometimes it may drop the wind and then boost it dangerously. Quite a few kiters actually went in to rig larger kites only to go out in nuclear conditions when the storm clouds arrived. You can get an idea from what it has been doing upweather as to what it "may" do when it reaches you. It could be stronger or milder of course but it really pays to check out weather online upweather.
7. Squalls frequently cause the wind to change direction by about 90 degrees or violently change directions stalling kites. This can take reasonable side shore winds and shove them offshore. Kiters have been lost several times due to this predictable wind shift. Even more kites and boards have been lost. The wind shift happens even without squall lines with passage of "dry fronts" and can happen when regional winds take over at the end of the day from coastal "thermal winds" or sea breezes. Sea breezes also can come with a squall line that may move towards the sea increasing the wind as it does, see below. Aside from an obvious lightning hazard these thermal squall lines also can pack some real severe storm activity all be it short as well.
8. Riders hit with sudden high winds often fail to properly Emergency Depower their kites. Few practice it sufficiently to provide much assurance of success anyway. A great deal is riding on you doing what you need to do in very little time with everything working as intended in the midst of dangerous squall gusts. It hasn't worked out well for quite a few in the past. Ignoring these weather hazards or being struck Wind Dumb** is not a good option.
9. Given the uncertainty of how things will work out in a squall the logical conclusion is to avoid it and by a good margin of time. Lightning, gust fronts can reach out well ahead and you never know if you might be slowed down in landing and securing. REGULARLY PRACTICE what you would do mentally and physically with kite, quick releases, etc.. in a high wind emergency just in case you really screwup and drop yourself in it despite strong efforts to avoid squalls. Most never bother to do this seriously and so may set themselves up for a real bad experience some unfortunate day.

10. Some say to go offshore in squalls to "ride it out like a bluewater ship." When was the last time you saw a ship lofted 300 ft.? I suspect this has never happened. The reasoning is that if you stay away from the hard stuff you will be OK. Reason and the accident experience don't support this. Instead get in early and secure. We aren't ships, not remotely close particularly in how high winds deal with us. A kiter, who survived, was lofted 1200 ft. in a 25 kt. squall gust?! How far offshore are you going to go? Also there was another kiter lofted off the water smashed to unconsciousness and near drowning in a 35 kts. squall gusts (shown above at time of water impact). The key to squalls is to NOT be in them and with time to spare, react early in other words.
We may not see pigs (or ships!) fly but kiters can do it easily, and worse to harm in excessive winds all too commonly.

Don't mess with squalls, avoid them with a passion. Anticipate them, land and secure early. Secure ideally means to put your gear away. I saw a kite traveling offshore yesterday in a normal 90 degree wind shift, likely lost forever. If it had been rolled up, at least with the leading edge deflated and lines detached it might not have left the beach. Wait until signs indicate it is ok to go out again. Often there can be a post squall low, that effectively kills the wind anyway. It isn't that hard to do as a rule and the consequences of ignoring them can be dire.
** Wind Dumb - AJ used this term recently, I hadn't heard it before. I would assume it is the blurring normal judgment in the revels of wind lust. It allows us to go out into conditions we don't understand sufficiently or could reliably handle even if we understood them well. I think many of us may have been susceptible at some time, but a bit of knowledge and common sense will likely see you past it. If you think you can handle it, view the video at the link below and answer again if you know that you could or that it is worth your good health or life if not. This is a fairly extreme wind event, lots of kiters have been lost and maimed in substantially less, half even lower wind from squalls.

^^^ Be sure to checkout what is above this first. ^^^
So, what happened yesterday? Lets have a look ...
Had another cold front squall line yesterday, bringing winds gust to 40 to 60 mph +, tornados, waterspouts and offshore wind shifts. This was the second violent front in a week. Many dozens of kiters have been killed in these worldwide and likely hundreds injured including paralysis, brain trauma, major and minor bone fractures along with damaged or lost gear.
Kiters still go out in them due to a lack of apparent understanding and respect for just how easily and badly they can be messed up. Gear has improved but not enough to allow you to risk this sort of violent weather.
These squall lines are usually easy to see and avoid. Some people just don't try or ignore them. This squall line could be seen days out working its way across the country and causing damage along the way.
You could see it was going to be a bad one before 8 am way up near Tarpon Springs above Tampa that morning through radar, real time winds and hazard forecasts.
Driving northward through Boca Raton, FL along the coast at 1:45 pm when the squall line passed over.
The wind spiking in Royal Palm and at Port Everglades in Ft. Lauderdale.
It was slamming through South Florida hours later, spiking the wind into the 40 to 55 mph range. The hazardous winds usually passed within an hour, this time. Sometimes they take longer.
I stopped at Delray Beach to shoot a shelf cloud that was flowing out to sea. Apologies for the poor stitching job, something about these images is confounding several different pano applications. I had to use a Droid-X telephone for the images, usually not that bad in a pinch.

This is a short interesting video of the same cloud drifting seaward under a sudden strong west offshore wind.
I saw something about 3/8 mile offshore and couldn't quite make out what it was other than it was heading offshore in the face of the squall. I almost called the USCG thinking it might be a disabled kiter, windsurfer or ? I asked a couple of kiters who set me straight. It was someone's kite, inadequately anchored for a 90 degree wind reversal boosting to 35 kts., imagine that, that was ripped from shore likely to be lost. The only sure way to secure kites before a storm is to roll them up or at least take the lines off and deflate the leading edge well anchoring it with sand. Wouldn't it be interesting if someone got caught in the lines of a powered up kite heading offshore? A kiter died of hypothermia in CT after chasing his kite a short distance offshore in the face of a similar squall line wind shift. He was adrift in the dark perhaps for ten hours in December before he succumbed.
There is a lot to know about weather or take it more basically. Do your weather planning and monitoring, if something threatening moves in, land and secure EARLY. Don't screw around, a percentage of us will pay, some dearly for staying out too long.
