An update to the GFS-MOS
(TIN 07-42)
including the addition of new stations to visibility, obstruction to vision,
and probability of precipitation characteristic guidance will impact certain GFS-LAMP elements. Effective 9/11/07,
there will be GFS-LAMP forecast guidance at additional stations for visibility, obstruction to vision, conditional visibility,
and precipitation characteristics. This will alter the GFS-LAMP BUFR Product and add lines to the GFS-LAMP
Text Bulletin (LAV). More details

Corrected a problem with the thunderstorm graphics for the new GFS LAMP cycles implemented 5/9/2007.
There was a bug in how the guidance for some projections was being displayed. This fix required
changing the thunderstorm guidance graphics page from a shtml formatted page to a php formatted page,
which necessitated a change in the URL.
