The Aviation Weather Center (AWC) provides weather information and forecasts for air flights over United States territory and at certain altitudes for global traffic.

It works with customers, such as commercial airlines, and international partners to improve flight safety and efficiency.

Each local NWS office issues Terminal aerodrome forecasts (TAFs) for airports under its area of responsibility.

[1] The AWC is also responsible for aviation warnings, such as AIRMETs and SIGMETs, for the United States, including its overseas territories, and northern portions of the Atlantic and Pacific Oceans.

[1][2] It is finally the center that issues forecasts for the displacement of volcanic ash and forest fire smoke plumes for the same territories.
