I recall reading the NWS at some point would assign a SAME code to every
product they have and precede all messages on the NWR with a databurst
so receivers could un-mute on a given PIL. AFD being the Area Forecast
Discussion. Not sure about their use in LV area other than as the twice
daily discussion (with updates interspersed).
PDS is a sub-type of product known as a Particularly Dangerous
Situation. PDS signifies and elevated threat level of both severe
weather occurrence and strength of the event(s). When those are issued,
there's a pretty good chance significant and widespread severe is expected.
The NWS has also started using a Tornado Emergency message
type/product. Not sure of it's real meaning other than call attention
to a significant tornadic event in progress. Never the less, the TOR is
the official call to action message.

I suppose it is possible that their encode equipment put the wrong code in or a relaying encoder parsed the message wrong twice and passed it incorrectly parsed? Or maybe an "Area Forecast Discussion" somehow became SAME encoded?
