What does a Center Weather Advisory primarily report?

A Center Weather Advisory (CWA) is designed to provide timely information to pilots regarding significant weather conditions that could affect their flight path and safety. This advisory is issued on an unscheduled basis and focuses on immediate weather phenomena, such as turbulence, thunderstorms, or severe icing, which are pertinent to aircraft operations within a specific airspace.

The primary purpose of a CWA is to ensure that pilots are informed of current weather hazards, allowing them to make informed decisions for their flight operations. The emphasis on immediate conditions distinguishes it from detailed weather observation reports or long-term forecasts, which do not provide the same real-time situational awareness. Therefore, the choice accurately reflects the nature and intent of a Center Weather Advisory.
