Just a quick update: we survived the night.
Irma did us a huge favor. She turned just a bit north and the eye was 100 miles away by the time she passed out end of the island. We had strong gusty tropical storm force - not hurricane - winds.
A little over a third of the island is without electricity, including us. But we still have water as of now which is more important.
Our dogs were understandably anxious - new surroundings, new sounds, a storm - but they are fine. We're heading out now to check on the house and they onto see the horses.
More later as we can.
