Rainfall for the whole year as of today is only 13.73 inches. She went missing June 1, so 5 months ago. At an average of an inch per month, that's 5 inches total. None of the tropical storms or hurricanes have gotten close to Aruba, if that's what you're thinking. They are out of the zone and it's generally an arid island.
As far as the sea tides and currents in the Caribbean around Aruba, that's a little different story, since the storms do affect those. Everything depends on if she is weighted down if her body were thrown from a boat. I'd hoped that they might find out from someone's confession where the vessel might have gone.
If it was 12 miles offshore or more, that is international waters and we, the US, could have control of the investigation. In fact, international waters are only 2-3 miles offshore in the direction of Venezuela, because of treaties with that country, but I'm afraid that if they were in that part of the sea, they weren't dumping a body, they were taking a live girl into captivity.
I leave this case alone for a while because it's so frustrating, then I come back and get frustrated all over again. LOL, I still wear my little baby-blue rubber "Hope for Natalee" bracelet everywhere here in the Big H, but it was getting kind of old having people ask me if I am a Katrina refugee, or worse yet, they just look down at the bracelet and ask if I'm from New Orleans.
