We predict the existence of rogue waves in Bose-Einstein condensates either loaded into a parabolic trap or
embedded in an optical lattice. In the latter case, rogue waves can be observed in condensates with positive
scattering length. They are immensely enhanced by the lattice. Local atomic density may increase up to tens
times. We provide the initial conditions necessary for the experimental observation of the phenomenon. Nu-
merical simulations illustrate the process of creation of rogue waves.
