GEMPAK users, I have updated the watchbox pattern/action in the online examples for dcwtch for GEMPAK 5.6.E.1 which follows the change in WMO headers: http://www.unidata.ucar.edu/packages/gempak/tutorial/pqact/decoders.tbl The pattern for dcwtch is now: WMO ^(WWUS(40|08)|WOUS20|WWUS30) .... ([0-3][0-9])([0-2][0-9]) this change is necessary in order to decode the watch box bulletins for plotting in GPMAP and NMAP/2. Steve Chiswell Unidata User Support
