At present, there are thirteen Regional Warning Centres distributed around the globe. These centres are located in China (Beijing) , USA (Boulder), Russia (Moscow), India (New Delhi ), Canada (Ottawa), Czech Republic (Prague), Japan (Tokyo), Australia (Sydney), Sweden (Lund), Belgium (Brussels), Poland (Warsaw), South Africa (Hermanus) and Brazil (São José dos Campos). The European Space Agency (Noordwijk) is a collaborative expert centre providing a venue for data and product exchange for activities in Europe. In addition, the Associate Warning Centre in France (Toulouse) provides specialized services to customers, and is affiliated through RWC Belgium. A data exchange schedule operates with each centre providing and relaying data to the other centres. The centre in Boulder plays a special role as "World Warning Agency", acting as a hub for data exchange and forecasts.

Users of the services of RWCs include: high frequency (HF) radio communicators; mineral surveyors using geophysical techniques; power line and pipeline authorities; operators of satellites and a host of commercial and scientific users. The increasing sophistication and sensitivity of modern technology has resulted in a steadily expanding range of applications where a knowledge of the solar terrestrial environment is important.
