Latest Text Summary



During the 3rd dekad of June, the ITF continued its northward advance bringing early season precipitation amounts into the Sahel. Its position, on average for all regions, was barely below the climatological normal for late June. The western averaged ITF position (10W-10E) was approximated at 16.8 degrees North, shifting nearly 1.0 degree on average compared to the previous position during the middle of June. The average eastern position of the ITF (20E-35E) position of the ITF was approximated at 14.1 degrees North, slightly south of the climatological normal position (14.4) for the 3rd dekad of June. Figure 1 shows the current position of the ITF relative to its climatological position during the third dekad of June and its previous position during the 2nd dekad of June. Figures 2 and 3 are time series, illustrating the mean latitudinal values of the western and eastern portion of the ITF, respectively, and their evolutions since April, 2015.
