  Signatures of strong Anderson localization in the momentum distribution of a
cold atom cloud after a quantum quench are studied. We consider a quasi
one-dimensional cloud initially prepared in a well defined momentum state, and
expanding for some time in a disorder speckle potential. Anderson localization
leads to a formation of a coherence peak in the \emph{forward} scattering
direction (as opposed to the common weak localization backscattering peak). We
present a microscopic, and fully time resolved description of the phenomenon,
covering the entire diffusion--to--localization crossover. Our results should
be observable by present day technology.
