Did you look at and can you translate how the swell forecast will change the conditions in the White Bay anchorage? The change in swell that has traveled thousands of miles is the biggest threat once inside the anchorage. I short micro burst can be scary but manageable for the few minutes they normally last. Waking up to rollers is an entirely different animal. I was in Salt Whistle Bay, Mayreau one afternoon where the swell switch and in minutes all the cat on anchored in the shallow water ended up on the beach. The mono's in deeper water just swung and rolled. The cats were launched onto the beach. All in minutes.
