The physical nature of the very local (<3 Mpc) Hubble flow is studied on the basis of the recent high precision observations in the Local Volume. A model including both analytical treatment and computer simulations describes the flow dynamical evolution from a chaotic Little Bang initial state to the present-day state of a quasi-regular expansion. The two major observational parameters of the flow, which are the rate of expansion and the velocity dispersion, find a clear qualitative and quantitative explanation in the model.
