Yeah i believe that Slovenia is worth visiting in winter as well. Maybe it's not that great as in warmer days, but still a lot to visit. If you are lucky, you can get the Bled lake frozen and walk across to the island there.
I would say Snežnik is the last barrier for bora on this part. And the side from where the wind was blowing was directly from the sea. It was completely calm on the other side of the mountain. But bora is very common for the entire Adriatic region From Italy, Slovenia, Croatia and so on. And it can reach more than 200km/h. Search "pag bridge bura" on youtube :)
Thanks for your response I check it out on youtube it definetely is stronger than at the time I was in Trieste ... Anyaway it is always good to know something new! Enjoy your trips!!
