Absolutely. I subscribe to Summit Aviation's Aviation Reference Library and get quarterly updates. I'm sure that you can google
www.fcc.gov and search for Aviation Services/frequencies.
Flight Watch is indeed dead, but the frequency reverted to general FSS use. The frequency spectrum is so crowded that the luxury of just letting one go silent simply does not exist.
Once upon a time there was a position at Flight Service Stations dedicated to weather; the briefer assigned to that position did not do flight plans, did not answer general questions, did not do anything but weather. That position was called Flight Watch, and it had its own frequency. And it was successful.
But then technology intervened, and pilots suddenly had a multitude of choices when looking for weather information. The folks in the ivory tower decided that it was wasteful to have a briefer assigned full-time to weather when pilot requests for weather were declining....so they told the briefer "When you come to work tomorrow you are no longer Flight Watch, you are back in the herd as a general purpose briefer; remove that "Flight Watch" label from your switch panel next to 122.0."
And it was good. Thus endeth the sermon.
