En de tekst, ook wel zo makkelijk 
Serious rainfall risk may evolve with gradually deepening vortex and evolving deformation zone just over Belgium and the Netherlands. Inflow into this deformation zone features deep and very moist air mass with intense lift. Prolonged period of near quasi-stationary conditions of strongest convergent flow and aforementioned air mass quality rise the concern of widespread excessive rainfall. It's not yet clear, where strongest banding occurs, so the level 2 is still quite coarse. New model data may increase confidence later-on, where highest rainfall amounts occur.
