I started this as a new thread in consideration of the slower connections out there due to all the images. This builds upon the thread at:

On the next day, June 10, 2004 after Shannon's lofting, some REALLY heavy weather really came through, that makes 30 kt. gusts look like wimpy winds ...

NWS had this to say ...

Latest Severe Tstorm Warning by KTBW

... severe thunderstorms contain wind gusts of 60 mph or higher...and
hail the size of pennies or larger. move to a place of safety.


at: http://nws.noaa.gov/

I wonder if they are actually suggesting is to go out with a parachute like wind catching device the size of a car secured by 100 ft. lines and to wait for some violent 60 mph winds to come in ???

I was drving back to SE Florida through the central east coast area around Melbourne and saw this intense looking Shelf Cloud on the afternoon of June 10, 2004.

Shelf clouds can be associated with violent gusty unstable weather. More about these weather systems at:
http://weathersavvy.com/Q-Shelf_Roll_Clouds1.html

NOTE: SEVERE GUSTS CAN BE ASSOCIATED WITH FAR LESS OBVIOUS AND THREATENING CLOUD SYSTEMS THAN SHELF CLOUDS. So, learn what unstable weather looks like in your area and be on the lookout for it.
AND ... YOU MAY NEVER KNOW WHAT A PENDING SQUALL WILL HIT YOU WITH UNTIL IT UPON YOU. So, avoid them all. We learned what can happen with an 18 m kite in 30 kt. winds, wonder what would happen in double that speed?!

This is an interesting color radar image for that afternoon last week. Note the abundant bright red lines strung in varoius areas around the state. These red zones have the potential to toss out high (60 mph) gusts, tornados and lightening. It is impressive that these intense weather bands were so extensively distributed over the state. REMEMBER: these severe weather bans can come up VERY rapidly in otherwise clear weather. Things are going fine and then BANG, LOFTED!

A satellite image from the same afternoon. The abundant red areas represent strong weather systems.

The following wind grahps are from: http://www.ikitesurf.com/
A strong squall gust spike near Jacksonville, FL on this afternoon.

Now, going back in time, what sort of winds can squalls kick out?

Image

Another squall gust spike and a powerful one around 50 mph back in 2001 in Jupiter!


Image

Another 70 mph squall gust spike in Jupiter in 2000. Note the highly confused wind direction arrows at the top of the chart. These indicated characteristic, violent and rapid wind direction shifts and even reversals that can come with squalls. Look for spikes and confused directions BEFORE heading to the beach to ride along with color weather radar. I was hit by a 50 to 60 mph gust and lofted earlier this same day in Boca Raton, FL to the south of Jupiter.

Image

Two strong squall gust spikes in 2001 at Crandon Park, Miami in excess of 50 mph each.

Remember the guy lofted over 800 ft. and 100 ft. high by a 51 kt. or 60 mph gust? We have squall gusts that high and higher not that uncommonly, particularly during the summer months.

MORAL: KITEBOARDING AND SQUALLS DON'T MIX. AVOID SQUALLS.
Be aware of the weather or potentially be lofted.

NOTE: MOST AREAS ON EARTH have some form of violent, gusty weather at various times of the year. Learn what it looks like in YOUR area and what signs preceed its arrival.
