Latest Text Summary



From August 11-20, the ITF moved farther north compared to the previous decade. The mean position of the ITF is approximated at 19.3N, which represents a northward movement compared to the previous decade. Between 15W-5E, the ITF is still declined in the far west compared to the normal position which could explain the suppression of rain experienced over Senegal and south Mauritania. Between 5E-35E, the ITF has moved significantly northward expecially at 15E and between 35-35E.As a result, near or above average rainfall was widespread across Chad and Sudan during the dekad; which could explained the floods and landslides reported over the central west to east part of Sudan. Figure 1 shows the current position of the ITF relative to the long-term average position during the 2nd dekad of August and its previous position during the 1st dekad of August. Figures 2 and 3 are time series, illustrating the latitudinal values of the western and eastern portions of the ITF, respectively, and their seasonal evolutions since April, 2019.
