From J uly 21-31, 2013, the ITF advanced further north and nearly coincided with its long-term
average position across Africa. Vigorous southerly winds enhanced moisture and resulted in above-
average rainfall during the period across portions of the far west West Africa, including northern
Senegal and southern Mauritania. However, the ITFs mean western portion was slightly below-
average and trailed the climatological position by 0.3 degree. Farther east, strong southerly winds
also pushed moisture to the north, bringing seasonable rain over western Sudan and moderate to
heavy rain across Eritrea. The ITFs mean eastern portion was located approximately at 16.5
degrees North, which was to the south of the mean position by 0.1 degree. Figure 1 shows thecurrent ITF position relative to the long-term average position during the third dekad of J uly and its
previous position during the second dekad of J uly. F igures 2 and 3 are time series, showing the
average latitudinal position of the western and eastern portion of the ITF, respectively, and their
evolutions since April, 2013.
