In the fully nonlinear regime we derive the finite time scale of the singularity formation in terms of the characteristics of forcing. The exact probability density function of the one point height field is obtained correspondingly.19 pages, latex, two figures, corrected typosCondensed MatterHigh Energy Physics - Theorytext
