Look for the possibility of 2+" (5+cm) of rain on SBH on Sunday from the first tropical wave.
It's really too early to comment on the 2nd tropical wave, which will reach the Caribbean later in the week. The usual computer models don't predict that far ahead. Keep an eye on a site such as Weather Underground.
https://www.wunderground.com/hurricane/ At present, the tropical wave is still that, a tropical wave. What you want to keep an eye on is the wave which is presently designated 96L.
And yes, I would prepare for wet as JEK suggests, but I wouldn't have a "hunker down, it's a hurricane" mentality. I might add a rain hat to my bag, and perhaps even a rain slicker, but I personally wouldn't do much more than that, given what I see in the forecasts. If a tropical wave does come through, it will likely come and go in a day, so anyone vacationing next week is unlikely to have a washout.
I've had washouts (6 straight days of unending rain) in November. Attitude becomes important then. I was traveling with friends at the time, some of them hated it and had a terrible vacation, some of us adapted, figured out how to have fun in the rain, and moved on. The sun eventually came out, some went home as scheduled (my then-girlfriend with work responsibilities included), and some (me included) extended for an extra 3 days.
