Road closure in the Vipava valley (Vipavska dolina) due to Bora (strong wind)

The information which can be seen here on exceeded limit values of wind strength is intended for orientation and as initial information to drivers.

Individually exceeded limit levels do not automatically mean that a road is closed or traffic is restricted. A decision on road closure is taken on the basis of information currently available, the detected trend of wind strength and past experience.

The traffic on roads is restricted when wind speeds exceed a threshold level and the increasing speed of wind is detected.
A road closure ends when the decrease of wind strength under a certain threshold level is detected.
