A hydro-climatic advisory has been developed as the outcome of a collaborative research project on producing useable climate information for water resources management in a decade-long collaboration between the Mahaweli Authority of Sri Lanka (MASL) and the International Research Institute for Climate and Society (IRI) at Columbia University. Our institute, the Foundation for Environment, Climate and Technology (FECT), grew out of this and subsequent projects. Over the last four years, FECT has produced weekly hydro-meteorological advisories for Sri Lanka for the Water Management Secretariat (WMS) of MASL. The WMS convenes a multi-institutional panel for water management and this advisory is consulted at its weekly water management panel. This hydro-meteorological advisory incorporates inputs from Sri Lanka Department of Meteorology, India Meteorological Department (IMD), IRI and the National Center for Environment Prediction (NCEP) of National Oceanic and Atmospheric Administration (NOAA). The monitoring section of the report provides satellite derived rainfall estimates at daily, decadal (10-day) and monthly rainfall estimates, weekly average Sea Surface Temperature anomalies. The prediction section is based on predictions from IMD, NOAA and NCEP and, seasonal predictions from IRI, European Center for Medium Range Weather Forecast and APEC Center. These predictions are from 3 days to 3 months ahead from the above agencies and scientists including our own. Objective skill assessments are underway for these predictions. We have provided these advisory to the MASL water panel over the last four years and have consistently been encouraged by the Mahaweli water managers. This product is available at our websites http://www. climate. lk and directly at http://fectsl. blogspot. com. Further enhancements of this advisory is under development. Following the success of this work, at the request of the Maldivian Ministry of Environment, we are now providing a monthly advisory for Maldives with the Maldivian Meteorological Service at http://fectmv. blogspot. com
