Special emphasis is given to weather conditions that would be hazardous to aviation or would impede the flow of air traffic in the National Airspace System (NAS). CWSU meteorologists also issue two unscheduled products: 1) The Center Weather Advisory (CWA) is an aviation weather warning for thunderstorms, icing, turbulence, and low IFR ceilings and visibilities.  And 2) The Meteorological Impact Statement (MIS) is a 2-12  hour forecast for weather conditions which are expected to impact ARTCC operations.
