In some axion dark matter models a dominant fraction of axions resides indense small-scale substructures, axion miniclusters. A fraction of thesesubstructures is disrupted and forms tidal streams where the axion density maystill be an order of magnitude larger than the average. We discuss implicationsof these streams for the direct axion searches. We estimate the fraction ofdisrupted miniclusters and the parameters of the resulting streams, and findthat stream-crossing events would occur at a rate of about $1/(20 {\rm yr})$for 2-3 days, during which the signal in axion detectors would be amplified bya factor $\sim 10$. These estimates suggest that the effect of the tidaldisruption of axion miniclusters may be important for direct axion searches anddeserves a more thorough study.
