programmes, facilitating the flow of data and processed products to meet requirements in a
timely, reliable and cost?effective way, ensuring that all Members have access to all
meteorological and related data, forecasts and alerts. This secured communication network
enables real?time exchange of information, critical for forecasting and warnings of hydro?
meteorological hazards in accordance with approved procedures.diagram
