I, too, was there in mid Sep, 2008.
According to my old calender, bet the 17th and the 20th, there were some major thunder storms which caused terrible mud slides and a lot of flood all over on Culebra as well as on the main island.
I was told that it was a rare occurrence in some 100 years or some long time.
The mud slides made the ocean so muddy for days and people didn't want to go in the water.
So I guess the weather was unusual at the very time and you must have encountered a rare occasion!
