|  Change in some TAF Valid Times
[IMG]file:///C:/DOCUME%7E1/Tom/LOCALS%7E1/Temp/moz-screenshot-4.jpg[/IMG] http://aviationweather.gov/notice/taf30.php 
" On November 5, 2008 a change in the Aerodrome Forecast (TAF) will occur that introduces a date/time element in the body of the TAF including the change groups for all TAFs provided by the NWS. This change in format is necessary to meet the service requirements as defined by the International Civil Aviation Organization (ICAO) to provide a 30-hour TAF to support flight planning requirements for long haul flights. A group of experts evaluated various options and concluded that, for safety purposes, all TAFs should adhere to a generic format regardless of the validity period of the TAF. The National Weather Service (NWS), at the request of the FAA, will provide a 30-hour TAF for 32 airports."
How do they think they are going to put out a 30 hr TAF when they can't even get the 24 hr TAF's correct? Heck, a lot of time they don't even come close within six hours!

NWS TAFs are done by the interns. if you want an accurate TAF get the one from your nearest naval airfield. | |

Why 30 hours? Where does that number even come from? Seems to me 36 would make more sense.... Does anyone even know?
If it ain't broke, fix it till it is... | |
