The decoder reads the warning text and saves the direction, speed, observed location, warning counties and lat/lon polygon pairs. The decoded information is stored as ADDE point data objects which can be plotted directly with PTDISP. The listing application (TORLIST) and plotting application (TORDISP) provide formatted output of these warnings. Here is an example of a warning decoded this AM http://cimss.ssec.wisc.edu/~russd/samples/TEST.GIF TORDISP is used to plot the Lat/Lon polygon region (black border with yellow outline) and the projected path is plotted as a white line segment. I noticed in the text of the linked document, that the polygons are described as a new feature. I have been decoding the Tornado Warning messages for the past 5 years and there have been lat/lon pairs included in nearly all of the warnings that I have seen. I'm wondering if the NWS intends to supply a separate polygon set in addition to the current text warning messages?

Applications: TORDEC - common language tornado warning decoder (keyin application) TORLIST - lists decoded Tornado Warning messages (ADDE application) TORDISP - plots decoded Tornado Warning messages )ADDE application) Data files DATOR - Tornado Warning MD file Scheme TORWARN.CORE - Tornado Warning application context file TORDEC.CFG - Tornado Warning decoder configuration file You should receive this through Unidata.

As for supplying a separate polygon set, I don't know. ******************************************************************************* Gilbert Sebenste ******** (My opinions only!) ****** Staff Meteorologist, Northern Illinois University **** E-mail: address@hidden *** web: http://weather.admin.niu.edu ** Work phone: 815-753-5492 * ******************************************************************************* ------- End of Forwarded Message
