Which organization provides Weather Advisory Broadcasts and alerts such as Convective SIGMETs?

The National Weather Service (NWS) is responsible for providing Weather Advisory Broadcasts and alerts, including Convective Significant Meteorological Information (SIGMETs). These broadcasts are critical for aviation safety as they offer pilots and air traffic controllers important real-time information about severe weather conditions that could affect air travel.

The NWS disseminates various weather advisories that inform the aviation community about hazardous weather phenomena, enabling enhanced decision-making for flight operations. Convective SIGMETs, specifically, are issued for thunderstorms that can produce severe turbulence, hail, and other hazardous conditions that directly impact flight safety.

While Air Traffic Control Centers (ATCC) and the Federal Aviation Administration (FAA) play significant roles in air traffic management and regulatory oversight, they do not issue weather advisories themselves. The FAA may use the information provided by the NWS to support their operations and ensure safety but is not the source of meteorological alerts.

It’s also important to note that Air Route Traffic Control Centers (ARTCC) manage en route air traffic, but they too rely on the National Weather Service for crucial weather-related information. Therefore, the correct source of Weather Advisory Broadcasts and alerts, including Convective SIGMETs, is indeed the National Weather Service.
