  We calculate the evolution of a jet shower due to medium induced splittings
in the deep LPM regime. Due to the characteristic energy dependence of the
formation time $t_{\rm form}(\omega)= \sqrt{\omega /\hat{\bar{q}}}$, the
radiative break-up process exhibits turbulent characteristics, allowing for
analytic predictions of various inclusive properties of the medium induced
cascade in an inertial range of energies $T \ll \omega \ll E$, where $E$ is the
energy of the jet and $T$ is the temperature of the medium.
