Hello, I was wondering if there exists a list describing what possible NWS 
alerts could fall into specific file extensions.  For example, I have files 
with the following file extensions:
FFA, FFW, FLS, NPW, RFW, SVR, SVS, TOR, WSW
And currently have captured alerts with the following in their VTEC:
FFA:    FA.A FF.A FL.A
FFW:    FF.W
FLS:    FA.W FA.Y FL.W FL.Y HY.S
NPW:    EH.A EH.W FG.Y FR.Y FZ.W HT.Y LW.Y WI.Y
RFW:    FW.A FW.W
SVR:    SV.W
SVS:    SV.W TO.W
TOR:    TO.W
WSW:    WS.W WW.Y
But I doubt this is complete.  Does someone have a complete list, or a location 
where it can be found?
Thanks!
Regards,Joseph Spenner
