The eastern (20E-35E) portion of the ITF was approximated at 11N, which led the climatological position by 0.4 degree. Figure 1 displays the current position of the ITF relative to the long-term average position during the 3rd dekad of October and its previous position during the 2nd dekad of October. 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 the beginning of April, 2021.
