One key factor for the formation of tropical waves is the intertropical convergence zone (ITCZ). It has shifted farther north than usual.

This, combined with a record positive North Atlantic Oscillation (NAO), has altered weather patterns across the Atlantic and Africa. This shift has led to more rain in regions like the Sahel and the Sahara Desert, where Mali and Mauritania are located. And so far, fewer hurricanes.
