eric, that is a newspaper story, and has much to do with what actually happened
as any other news story. Weather just does not and can not develop that quickly. Besides you can tell the reporter was fictionalizing when s/he slipped in that part about Few of the participants noticed an area of dark sky emerging behind them you also can tell that by blasted by a wall of water huh? what "wall of water" is that? most of the rest of the rhetoric in the story is the reporter "adding drama", as the phrase goes in journalism school. as far as the rest of that goes, one day a few years ago four people died in a thunderstorm in the waters I normally sail when a thunderstorm came through packing 90+ knots of wind. Many boats on the water damaged. My boat was not. Why? because I didnt go out that day knowing full well the chances of very high winds. I expected the high winds about 2:00, and they hit about 4:00. This ain't rocket science. Those dark clouds mean *something* and if they are traveling to the north of you you might be in for a bit of trouble. Plan for it. And being out in potential storm conditions in a lightweight racing boat means you have to keep your eyes open. buuuuuuuuuuuuuuuuuuuuuuuuuut, if it makes you feel better carry a baby blanket and a binky. The storm On May 6, 1989 around 1:00 p.m., 93 sailboats were underway in a large regatta on Lake Norman. By all accounts it was a "bluebird day" -- no clouds, medium-heavy breeze (12-18 knots). A perfect day for a sailboat race. While the NOAA forecast had called for possible thunderstorms late that afternoon, no one expected severe weather. At about 12:30, NOAA issued a "microburst warning" for the area. By then, the regatta was well underway. Everyone was watching their sail trim and their competitors. Most of the fleet was on a long down-wind leg. Few of the participants noticed an area of dark sky emerging behind them. Ten minutes later, the fleet was blasted by a wall of water and winds officially clocked at 64 – 78 knots. * Two sailors drowned. * Nineteen sailors were swept overboard and had to be rescued. * Four boats sank. * Sixty-two boats were substantially damaged. On Lake Norman -- a nice scenic inland lake (sound familiar??), two and one-half hours from SML. Survivors described the conditions thusly: * "A wall of gray—30 feet above the water, roaring towards us." * "The lake itself seemed to be lifted from its bed." * "A mixture of lake water, rain, and hail blew like a firehose." * "Seven foot waves broke over the banks." One sailor, suddenly aware of the storm, tried to drop his sails, but the sudden heavy pressure locked the halyards. He was knocked down with shredded sails. Another sailor tried to secure his companionway during a knockdown, but water was already pouring in the cabin. His boat sank. Many boats were either demasted or lost sails. |

Right, Jaxie, a line squall isn't visible at a distance through the warm, humid
air the precedes it. And fast moving lines often don't develop the tradition "anvils," and when they do occur they pop up fairly quickly. When a front is coming through, its nice to be able to visualize the "prefrontal squall line" to know what's coming. "JAXAshby" wrote in message ... There are lots of places where people sail and it's difficult to see a thunderstorm coming bull****. Thunderstorm clouds go as high as 60,000 feet sometimes, which means they can be seen up to 300 nm away. Even 10,000 foot high clouds can be seen up to 122 nm away. Can't see that coming? And there are many places where the potential exists every day in the summer thunderstorms don't form inside of 30 seconds. You *KNOW* they are coming, if one just pays attention. |

you're right, jeffie, thunderstorms appear out of nowhere and do so in less
than 9.87595957595 minutes. Do spend money on a service to tell you a thunderstorm in coming 'cuz you shore ain't never gonna tell othewise. Thunderstorms, theys God's way of tellin' ya hes gonna getcha. On the other hand, some people feel thunderstorms are Darwin's way of improving the breeding stock.

right, jerry, in the Chesey the REALLY strong winds in a thunderstorm are in
the NW quadrant, and the storms move in from the NE. The rest of the n. hemisphere follows its own path.

Radar for weather at NIGHT Was Radar on a cell phone
Hmm.. I have rarely seen T-storms at night, course my eyes are not that good
as some. Foregoing Vitriol, raving and puffery deleted.. As part of keeping your log with regular observations at say even bells. SOP in Lioness is to plot position and sweep the radar to look for vessels and thunderclouds. With 48 mile range you do get a good warning. A cell phone that gave you a message on weather would be nice, yet does not work offshore. Course if all you do is sail in category 4 water it is no biggie. Sheldon |
