Global Water Hazard Alarm System

Executive Council of the WMO, at its 69th session, recognized that life jackets have been demonstrated to be very effective in reducing loss of life and that there is a necessity that information about how to choose life jackets should be made more easily available for decision-makers in different levels, including the United Nations humanitarian agencies and the general public.

Therefore it endorsed the GMAS vision to be recognized globally by decision-makers as a resource of authoritative warnings and information related to high-impact weather, water, ocean and climate events.

The concept of the GMAS and its implementation plan, including the identification of users’ requirements, is being developed for consideration in the Executive Council 70th session in 2018.

The idea of GMAS’s future functionalities includes the platform for gathering the warnings from authorized national authorities, in particular National Meteorological and Hydrological Services, who are recognized as both stakeholders and potential users as the ultimate condition for GMAS is to use only official warnings.

Support for humanitarian actions of UN institutions has been identified as the priority of GMAS development (see analysis of extreme values, in Russian)

The intention is to provide UN bodies with warnings from NMHSs and other relevant WMO products to enable them plan and coordinate their activities efficiently without the need for searching for alternative information sources. As a result the visibility of NMHSs should increase.

In the second step, a discussion on necessity, possible forms and means of providing warnings to the general public using GMAS is considered.

The leveraging of existing activities and mechanisms of WMO, in particular discussion with Regional Associations and Technical Commissions is recognized as a critical component of an implementation plan to prevent duplication of effort to contribute to Sendai Framework for Disaster Risk Reduction target G on increasing the availability of early warning information for public.

Commission for Hydrology was represented at October GMAS meeting by responsible AWG member to promote hydrological services’ needs for future GMAS. What can you do concerning GMAS?

1)            Ensure that your hydrological service is listed in Alerting Authorities database as the institution responsible for flood warnings (or warnings for other phenomena). Editing of National entries of the database is done by National Meteorological Service in Your country.

2)            Contact AWG member Jan Danhelka at danhelka@chmi.cz with your requirements and needs as potential user and stakeholder of GMAS (what benefits would you expect from sharing your warnings via GMAS, what limitations and conditions you see for GMAS implementation etc.).
