Kavalo,
I have read and reread it. That's why I am asking the question.

The Jep chart also has actual and forecast minima. However there is no regular TAF service.
Again even if you get a special on request TAF the para in DAP I qouted means you do not add the 50 feet. There is no corresponding (that I can find) dap introduction notes 1.11 in Jepp. Now that is probably a Jepp translation error and not an error in the source AIP.
