Coronal mass ejections (CMEs) are key drivers of magnetospheric storms at Earth. Two key structures in CMEs are the turbulent sheath and the magnetic flux rope with smoother variations of solar wind plasma and magnetic field parameters. In this presentation I will discuss the status and challenges in predicting in advance (at least half-a-day) geoefficiency of flux ropes and sheath regions. The key focus will also be on observational and data-driven modelling efforts at the University of Helsinki space physics team to predict the magnetic field characteristics of flux ropes.
