Following the update of the agro-hydro-climatic forecasts made in July 2017, the perspectives for the cumulative rainfall, ending dates of the season and river basins flows for the 2017 season remain broadly unchanged from the conclusions of the Seasonal Forecast Forum held in May 2017 in Accra, Ghana. As for the onset dates of the season and the durations of the longest dry spells during the crop installation phase, they were generally confirmed by the field observations and the analyses at the regional level.
