when I was coming to santiago from santo domingo wednesday evening, I ran into heavy rain from bonao to la vega. Then there was a patch on the highway right at the entrance of la vega (coming from Bonao) where it seemed like a tornado had touched down. A huge tree had fallen on the highway, covering the whole santiago bound lanes. Then there was destruction of other trees and branches on the road. So I am not too sure about santiago, but this area was surely hit.
