Where is HIWAS information typically located?

HIWAS, or Hazardous Inflight Weather Advisory Service, is typically associated with VOR (VHF Omnidirectional Range) stations. The HIWAS information is broadcasted over these stations to provide pilots with timely information about hazardous weather conditions such as significant weather events, turbulence, icing, and wind shear in the vicinity of the VOR. This makes it an important tool for pilots operating under Instrument Flight Rules (IFR) as it enhances situational awareness during flight. The information is available continuously and can be received within the range of the VOR's radio signal, allowing pilots to stay informed about weather conditions that could affect their route.

The other options reflect locations that do not specifically broadcast HIWAS information. While air traffic centers are involved in managing traffic and providing services to pilots, they are not the sources of HIWAS broadcasts. Similarly, airports and approach control service areas may provide different types of information but are not the specific locations for HIWAS dissemination.
