Aviation Weather Center

What Aviation Weather Center does

The Aviation Weather Center (AWC) is a specialized division of the U.S. National Weather Service (NWS), operating under NOAA within the Department of Commerce. Located in Kansas City, Missouri, AWC provides authoritative aviation weather forecasts, observations, and advisories for the National Airspace System and international flight operations. Its product suite includes the Graphical Forecasts for Aviation (GFA), an interactive mapping platform displaying real-time METAR/TAF observations, PIREPs, satellite and radar imagery, and forecasts for turbulence, icing, winds, clouds, precipitation, and thunderstorms. Advisory products include SIGMETs, G-AIRMETs, and Center Weather Advisories, while specialized decision-support tools include the Terminal Weather Dashboard, Winter Weather Dashboard, and Ceiling & Visibility Dashboard. The platform covers CONUS, Alaska, Hawaii, the Gulf of Mexico, the Caribbean, and portions of the Atlantic and Pacific Oceans, with global reach via WAFS grids issued jointly with the UK WAFC.

AWC's underlying technology integrates data from over 140 NEXRAD radars via the Multi-Radar/Multi-Sensor (MRMS) system, GOES satellite imagery, numerical weather models (GFS, RAP, NDFD), and global WAFS data. Convective forecasting products include the Traffic Flow Management Convective Forecast (TCF), Extended TCF (eTCF), and Extended Convective Forecast Product (ECFP), which support FAA and airline operations for traffic flow management decisions. Data access is available through the AviationWeather.gov web portal, a Data API (overhauled September 2025), and the WIFS service for international flight operations. The platform underwent a major website overhaul in October 2023 and an API modernization in September 2025.

As a U.S. government agency, AWC operates on a non-commercial revenue model, providing all products and data free of charge as a public service. Funding flows through federal appropriations rather than commercial sales. Customer segments span general aviation pilots, commercial airlines, FAA Air Traffic Management (ARTCCs and TMUs), software vendors integrating via API, and Helicopter Air Ambulance operators. The organization has no venture capital, private equity, or individual ownership, operating solely as part of the federal meteorological infrastructure under the authority of ICAO and FAA sanctioning for flight planning use.

Core offering

The Aviation Weather Center (AWC) operates as the official U.S. government source for aviation weather, issuing real-time observations (METARs, TAFs, PIREPs), hazardous weather advisories (SIGMET, G-AIRMET, Center Weather Advisories), turbulence and icing forecasts, convective weather predictions (TCF/eTCF/ECFP), and specialized decision-support dashboards. It distributes these products free of charge through the AviationWeather.gov web platform, a Data API, and WIFS for international flight operations.

Product overview

Aviation Weather Center (AWC) operates as a U.S. government weather service organization providing a comprehensive suite of aviation weather products through its web platform. The core product is the Graphical Forecasts for Aviation (GFA), an interactive map-based system offering real-time observations (METARs, PIREPs, satellite, radar) and forecasts (TAFs, turbulence, icing, wind, temperature, clouds, precipitation, thunderstorms). Supporting products include advisory services (SIGMET, G-AIRMET, Center Weather Advisories), specialized forecasts (TCF/eTCF/ECFP convective forecasts, WAFS grids, SigWx charts), and decision support tools (Terminal Weather Dashboard, Winter Weather Dashboard, Ceiling & Visibility Dashboard). Data access is available via the Data API. The platform serves the entire National Airspace System including CONUS, Alaska, Hawaii, and adjacent oceanic regions.

Emerging players

• DTN: A commercial provider of weather-driven operational intelligence including aviation forecasts, turbulence/icing products, and flight planning data. Directly competes with AWC's downstream use cases for commercial airline and business aviation dispatch, while often sourcing or layering on top of government data.
• ForeFlight: A leading general aviation flight planning and electronic flight bag application that integrates AWC's METAR/TAF, SIGMET, and convective forecast data into pilot workflows. Directly competes on user experience for GA pilots, while remaining dependent on AWC as the upstream data source.

Broad incumbents

• Jeppesen (Boeing): A Boeing subsidiary providing flight planning, navigation, and operational services that integrate aviation weather data (often sourced from AWC and other meteorological agencies) into commercial airline dispatch and cockpit workflows. Comparable as a downstream integrator of aviation weather for airline operations.
• AccuWeather (for Aviation):
