SIGWX Charts - High Level Significant Weather

High level significant weather (SIGWX) forecasts are provided for the en-route portion of international flights. NOAA's National Weather Service Aviation Center (AWC) provides a suite of SIGWX forecast products for the World Area Forecast Center (WAFC) in Washington, D.C. These products are used directly by airline dispatchers for flight planning and weather briefing before departure, and by flight crew members during flight.
