Radar on a cell phone
eric, this discussion is about --- radar on cell phones ---!!! *you* need
frickin' cell phone to tell you that there is a thunderstorm in the 'hood, *you* need to stay tied to the dock. Period. JAX, Apparently, in addition to not being able to think too clearly, you can't read very well. Surprising for someone who can see storm clouds from 300 nm away! I see thunderstorms most afternoons all summer. That is why it is impractical, if you want to sail at all in the South in the summer, to say that you are not going to venture out when there is the threat of a thuderstorm. I've seen enough of them to know that every now and then they do sneak up on you - not every one but it only takes one. Any tool that helps you avoid one is a tool worth considering. Eric (JAXAshby) wrote in message ... eric, it seems you have seen just two thunderstorms in your life, and one of them came "unexpectedly". Trust me, eric, thunderstorms don't just "happen". I doubt I have been surprised by one since I was 8 years old. If you could see it you would have 16 1/2 hours (and if it was only moving at 10 knots - that's pretty slow for a thunderstorm). The point is - typical visibility at the surface is 7 to 10 miles on a very clear day. With summer haze it is frequently much less than that. If the storm moves 20 miles an hour (not all that fast for a thunderstorm), 10 mile visibility gives me 1/2 hour. Moving at 6 knots, I can move my boat a little over three miles in that 1/2 hour. Eric (JAXAshby) wrote in message ... yeah, right. at 165 nm way an 10 knots speed it will only take 16-1/2 hours for a thunderstorm to get to you. FAAAAAAAAAAAAAAAAAAAAAAAAAAAAAR too quickly for you react. You really should buy a cell phone to tell you that a storm is on its way and may hit you sometime tomorrown afternoon. Gosh, maybe I need new glasses - when I'm in the Bay off Annapolis, I just can't see those clouds over Morgantown, West Virginia - a mere 165 nm away. In fact, from the top of Old Rag mountain at over 3200 feet, most days I can't make out Washington, D.C. a mere 70 miles away (needless to say, I don't do this in a sailboat). Maybe I need Lasik! Eric (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. |
