"Sail Flow" weather/conditions site

I searched this (NCKA) forum, and I was surprised I didn't get any results for this conditions site that I found in the Latitude 38 free sailing magazine (online at " 'Lectronic Latitude" or something like that):
 Sail Flow (name of location)
Has wind, waves, tides, etc.  Looks pretty good.  Will have to compare it to the dozen others available. And importantly, to actual conditions.

Been using this site for several years now. I have using the Hornet weather station as it is right next to ARW. A high percentage of the time it is real close to what I experience. The only area I question is the temp. It is probably more accurate than what I feel.
