Key Takeaways:

The "legacy" Traditional Alphanumeric Code (TAC) AIRMET for the conterminous U.S. is officially being retired, effective on or about January 27 at 1900Z, after a nearly two-decade-long effort to phase it out.
Graphical AIRMETs (G-AIRMETs), which were introduced in 2008 and became the operational product in 2010, will now serve as the sole official weather advisory for the conterminous U.S.
This retirement specifically applies to the conterminous U.S.; legacy AIRMETs for Alaska and Hawaii will remain unaffected and continue to be produced.
