About MRC’s Flood Forecasting


During the June-October flood season, the MRC’s Regional Flood Management and Mitigation Centre issues daily flood forecasts and warnings. Data from 146 hydro-meteorological stations is used to predict water levels at 22 forecast points on the Mekong River system.

Through the MRC home page summary graphic and dedicated Flood Forecasting Website, the Flood Management and Mitigation Programme (FMMP) communicates these daily bulletins to National Mekong Committees, non-governmental organizations, the media, and, most important, the public. The home page graphic provides an easy-to-read summary of the 5-day forecast along the Mekong River system.
