World-Wide Navigational Warning Service

NAVAREA III

Coordinated by Spain (Instituto Hidrográfico de la Marina); covers the Mediterranean and the Black Sea.

NAVAREA III covers the whole Mediterranean and the Black Sea, with a sub-area coordinator for the Black and Azov Seas. Spain's Navy Hydrographic Institute in Cádiz coordinates it. Firing exercises, submarine cable work and, since 2022, the drifting mines and hazardous-operation areas of the Black Sea account for much of what it broadcasts.

The in-force list is collected directly from the Spanish Navy's NAVAREA III pages; older warnings come from NGA's HYDROLANT relays. A Bulgarian mirror of the Black Sea sub-area was used until it stopped updating in December 2025.

What the archive shows

10,120 warnings in this archive are attributed to NAVAREA III, issued from 1999-01-05 to 2026-09-14. 17 of them are in force in the latest lists we collected.

25 come from the area's own series and 10,095 are NGA relays that name NAVAREA III as their source.

Exercises accounts for 4,898 of 10,120 recorded messages (48%), the largest warning type group in this selection.

The stations and services named as originators most often are WZ (49), SPANISH NAVY IHM (25), MARISICILIA (9) and CTG (5), among 41 in all.

The largest yearly count is 2020, with 1,326 warnings. Collection is incomplete between 2024-05 and 2026-08-17, so those years are not comparable.

They reached this archive through HYDROLANT (10,076), NAVAREA III (25) and HYDROPAC (19).
