The Alliance for Hydromet Development concluded its 2026 Annual Meeting in Lagos, Nigeria, WMO reported on 23 October 2026. The meeting, hosted by the Nigerian Meteorological Agency under the Federal Ministry of Aviation and Aerospace Development, ran from 13 to 15 October and was the first time the Alliance's Annual Meeting was held in Africa. It brought together governments, development and climate-finance institutions, national meteorological and hydrological services, regional and international organizations and the private sector.

Discussions identified three priorities for 2027–2028: mobilizing and coordinating investment, including turning Country Hydromet Diagnostics into investment-ready project pipelines; strengthening national institutions and sustainability through governance and predictable domestic financing; and advancing public-private engagement and innovation. Nigeria's NiMet described its partnerships across aviation, agriculture, insurance and maritime activities. NiMet Director-General Charles Anosike noted that Africa accounts for approximately 30% of the global deficit in basic weather and climate observations.

WMO President Abdulla Ahmed Al Mandous cited achievements since the Alliance's 2019 launch, including Country Hydromet Diagnostics and Hydromet Gap Reports, and the Systematic Observations Financing Facility established in 2021.
