  Lattice Weinberg - Salam model without fermions for the value of the Weinberg
angle $\theta_W \sim 30^o$, and bare fine structure constant around $\alpha
\sim 1/150$ is investigated numerically. We consider the value of the scalar
self coupling corresponding to bare Higgs mass around 150 GeV. We investigate
phenomena existing in the vicinity of the phase transition between the physical
Higgs phase and the unphysical symmetric phase of the lattice model. This is
the region of the phase diagram, where the continuum physics is to be
approached. We find the indications that at the energies above 1 TeV
nonperturbative phenomena become important in the Weinberg - Salam model.
