originally defined as a very strong, cold wind that blows from the northeast onto the Adriatic region of Italy, Slovenia, and Croatia. The word is from the Greek boreas, "northwind." It is most common in winter and occurs when cold air crosses the mountains from the east and descends to the coast. It often reaches speeds of more than 100 km (60 miles) per hour and has been known to knock people down and overturn vehicles.
