Experts from the Department of Water Resources (DWR) under the Ministry of Fisheries, Water Resources and National Assembly Matters (MOFWRNAM), have predicted this year’s rainy season to be normal and slightly above normal.
The experts made the disclosure on Tuesday May 14th 2019, at the aforementioned Ministry’s conference hall during the presentation of the seasonal rainfall outlook for 2019.
Experts also indicated that the 2019 seasonal hydrological forecast would be normal to slightly above normal flows in the Gambia River Basin, as a result of the usual floods expected in the upcoming rainy season.
Permanent Secretary Dr. Bamba Banja, said the forecast is the result of collaboration with the National Meteorological Services within the sub-region and beyond; that the seasonal forecasting relies on the prediction of averages over space and time, and may not reflect all the various factors that influence regional and national climate differences.
He said the forecast is relevant only for the entire season and within relatively large areas, since local and month-to-month variations may occur and rainfall results are usually expressed as being either below normal, normal, or above normal, with normal rainfall defined as the average rainfall during a 30-year period.
“The forecast is only valid for the combined period of July, August and September (JAS), when approximately 80 per cent of the total seasonal rainfall occurs in the sub-region, including The Gambia. Consequently, for the rainy season of JAS 2019, the forecast is one of normal, and most likely to above normal rainfall which is likely. This is a threshold of at least 580mm of rainfall in the Gambia,” he said.
