30 hours TAFS coming in November.
Excerpt from the above link
On November 5, 2008, with the 1800 UTC issuance, the NWS will change the TAF format to conform to international standards outlined in ICAO Annex 3. The change includes the initiating of 30-hour TAFs for high-impact U.S. airports. To accommodate the extended TAF period, the format of all TAFs will change.
Does anybody know what the criteria for “FRM” is when they describe significant and rapid change? I don’t see that much significant change in their examples provided in the page, (unless winds from 110 to 220 is considered significant?)
I would have thought it would have preceded the 0400 time frame from their example?
I wonder how many aviation related computer programs this will break in the English translations
