What type of advisory are unscheduled inflight, flow control, air traffic, and air crew advisory that is a supplement to an existing SIGMET, C-SIGMET, or AIRMET?

Center Weather Advisories are issued when weather exists or is forecast to occur that could affect en route flight operations but does not meet the thresholds for a SIGMET, C-SIGMET, or AIRMET. They’re unscheduled and provide timely, concise information to air traffic facilities and pilots, flagging weather hazards such as developing convection, turbulence, icing, strong winds, or reduced visibility that could impact flight paths or flow management. Center Weather Advisories are produced by Center Weather Service Units and are meant to supplement existing advisories, helping controllers decide on routing, delays, or other ATC actions without replacing the formal SIGMET/AIRMET/C-SIGMET products. Their unscheduled nature reflects rapidly changing conditions, ensuring crews and controllers have current operational guidance.
