How could this low form people are wondering? Well looking at the setup now, you have a huge anticyclone over the northern GOM that you can clearly see spinning away. It's going to move East and the unsettled weather in the Eastern Caribbean will get pushed into the Western Caribbean and ride around the periphery of the anticyclone. Once in the western Caribbean the activity moves into a more favorable environment and a low develops and moves off to the WNW then NW. A short-wave trough is forecasted to start digging down across the midwest and into the southern states in about 5 days. That will cause this low to eventually move north and then NE as it gets caught by the trough.
Note this is a "classic" mid to late October setup. What has happened in the MDR in 2006 is NO reflection on what could happen in the Western Caribbean albeit a moderate El nino may ameloriate the possibility of anything too catastrophic for the US. Watch the Western Caribbean over the next 7-10 days. If nothing forms by halloween I would say the threat has diminished. But until then we can't let our guard down despite how bleak 2006 has been for homegrown systems - in my opinion the Western Caribbean has been way too quiet this year.
