Motivated by both the apparent lack of local extragalactic UHECR source candidates, beyond Cen A, and the correlation of UHECR anisotropies with local extragalactic structure, we investigate a scenario in which these anisotropies are imprinted during propagation. Such a possibility builds on the idea that galaxies are enshrouded in an extended halo of hot gas, which we postulate is also magnetised, enabling these objects to scatter UHECR during their propagation. Telltale signatures of this scenario are considered.
