Be safe!!
As of Monday morning it looks as if the storm won't reach hurricane force winds until Wednesday or Thursday. So you will probably get tropical storm winds with the majority of the storm passing to your north which is the best situation for a close storm.
I know you follow Stormpulse, I also use Wunderground.com because of their good computer model forecast maps and Terrapin.com which seems to get the official weather forecast five to fifteen minutes before they're officially published.
What are your conditions now in Bequia? System is to your north are winds still from the east?
currently no wind at all.. expecting winds from the S tomorrow- we are pretty far from the system thankfully although we've got loads of rain and thunder
If your anchored where I think you are, and the winds are from the south the old fort point should be off your stern. I had what is possibly the best night dive ever there years ago. Full moon night, crystal clear water and lots to look at. With the full moon not even an underwater light was needed. Great fun, thanks for bringing back great memories with your travel. JG
