NOAA warning help #2

I must set my ZONE to one number less than the ZONE I want the warning for. I.e. to obtain warnings for #NCZ050. I must set the zone to #NCZ049

Looking at the Raw data it appears the actual warning is below the header:
cap:web
http://www.nws.noaa.gov/alerts/nc.html#NCZyyy.GSPSPSGSP.185600
etc.
for a zone #NCZyyy

In WD 10.23p it appears WD is displaying the warning above the header:
cap:web
http://www.nws.noaa.gov/alerts/nc.html#NCZyyy.GSPSPSGSP.185600
etc.
which id for NCZxxx… :?
