I just looked at the projected track, which could turn out to be it's real track, and I am not familiar with the East Coast
hurricanes, as my time in cyclone areas has been in the South Seas.
So my input will just be an event that happened to us. We'd been watching this low develop and saunter towards us: it did not at any time go to it's predicted location for a particular time. We charted the predictions and the observations. Finally, someone with a satphone heard a new prediction, it was going to come over our location. The next morning, we beat south in 40 knot
winds about 100 miles through the water
to a cyclone anchorage, arriving in those coral
infested waters about midnight. Used a friend's waypoints programmed to the autopilot
to get to the outer anchorage [a first and so far only time thing for us], that had boats in it. At dawn, we worked our way into the hole from the outer anchorage, buoyed the anchor
when we anchored (so late arrivals could avoid it) stripped the ship, and hunkered down to wait. It went elsewhere, in the end.
So I would say, keep a close eye on the weather
, but be certain your tackle is up to it, and that there will be somewhere you can go that will be safe. In bad weather, anchorages
fill up fast, and the people don't always agree on strategies or honor anchoring
rules. Consider that it is not those of us who suggest it MIGHT be okay for you to go who will have to pay for damage that could accrue. It could, indeed, wreck your 4th of July--either way. It may be that the guy who said forthrightly, "give it a miss" is giving you the very best advice of all.
I hope it works out well, whichever way you decide. "Today's misfortune is tomorrow's adventure."
