No, the NRL is not nuts. Lets not get into bashing agencies on this site. Confrontational posts seldom serve a useful purpose and they are not solicited on this site. Since meteorology is a constant learning process, here are a few tidbits to tuck away:

NRL initiates an Invest at the request of NHC and the Invest coordinates are provide to NRL by NHC.

Cold core extratropical systems can transition to warm core subtropical or tropical systems. Since one already has this year, it does not surprise me at all that NHC wanted to monitor this area with an Invest.

The decision on Andrea is old news - its history, and that decision was made by learned folks who specialize in tropical systems, and I believe that they made the correct call. Arguing its merits is better left to those that do post season analysis. Arguing it here will change nothing.
