Yes, much safer than living on the east and south coasts or in Samana. To get to you, a hurricane would have to go across the island. They sometimes do that, but more likely starting around Baharona and heading toward Haiti. When a hurricane passes over land, it always loses force. There is no warm ocean water it can get energy from and the rough terraine help to break up the storm. It may reform and gain more strength when it gets to the Atlantic Ocean, but when it passing over Jarabacoa, if it does, it will be much weaker.
To sum, the odds very much in your favor there will be no hurricane pass over Jarabacoa, and if it should, it will be weakened by the mountains and the passage over land.
