Thanks for the info but posting raw recon is of little help. Please post the decoded information. Very few people know how to read the raw data. I will be happly to supply you with a decoder if you need it otr anyone else for that matter.
I posted it so somebody else can decode it. But I believe the ob 12 was taken at 8:34 EDT at 13.4N 62.1W and they are reporting flight level winds from the SSE at 19knts. You can find out how to decode on the NHC site.

It's not that hard. In fact it's pretty simple once you get accustomed to it. Here I'll show you for future reference:
Look starting from the right, the third row. See it says...17019?
Well, that means that winds are coming from the SSE or 170 degrees which is the FIRST 3 numbers you see in that row and at a velocity of 19 knots which is the last 2 numbers you see in that same row. Remember this is flight level data ONLY. IF another row appears on the far right with a number starting in 4 then that means that surface winds were obtained and it will be shown the same way I said above. In this case, this report doesn't show any surface winds.

Great, what do the other numbers mean? I have a decoder to run the numbers through but i am trying to help the others.

I would suggest you take a good reading at one of the links above that were posted. To answer your question, I'll show you the basic things about TIME and LOCATION:
Don't worry about the first row as it is always that same number: 97779. Now, the second row is the time, specifically the first 4 digits. In the example above, the observation was taken at 1234 which is universal time or GMT, just subtract -4 to that time and you'll get Eastern Time. Third row...last three digits means latitude. In this case 134 would be 13.4N. Fourth row...first three digits means longitude. In this case 621 would be 62.1W.
Take a good reading at the links above as they do have good information.

This is very cool, to me, as one thing I am good at is reading directions...these directions even include a sample to try out, and make sure you are getting what each of the lines mean. There is a huge amount of info but you can get the basic meaning of the report pretty easily...if you take the time to click on HOW TO READ! This is found on the link I previously posted...
