I spoke to Tricia at Southwind at 10 a.m. e.s.t. Said the ferry is still open, and will be until noon today. She says it isn't bad yet, but some whitecaps inside the reef... She said that everyone is taking precautions, and they are ready. I think the general mindset is "Bring it on".
Keep us posted if you hear anything. My guess is that the island will lose phone and electric, so any word you can pass on is appreciated.
