Please keep the Virgin Islands and Puerto Rico in your thoughts and prayers. Even though he is "only" a category one hurricane it looks like he's going to pass right over the islands. And there is always the chance he could gain strength.
My mom and sister, my cousins and friends will probably be fine. Their homes are strong and have survived far worse than 75 MPH winds. It's the rain at this point that they don't need any more of. They've already had quite a bit from this system, before it turned into a hurricane, and have experienced some flooding. Still it's always a bit nerve racking for me as I wait out the storm from a safe distance.
Unlike people along the coastlines of the U. S. people in the islands cannot be evacuated, they have no place to go. They have learned over the centuries to hunker down and wait it out.
