Convergence in probability of stopping times

Let $(X^n)_n$ be a sequence of continuous real-valued stochastic processes in $[0,T]$, $T<infty$ such that for every $tin [0,T]$ $X^n_t$ converges in probability to $X_t$.
Let $tau^n=inf{tin[0,T], X^n<0}wedge T$ and $tau=inf{tin[0,T], X<0}wedge T$.
Why does $tau^n$ converge in probability to $tau$ ?
