Typically, October is a month when tropical activity dies down. The so-called "Cape Verde" season is practically over, as storms originating over the Saharan desert are no longer strengthening as they move into the eastern Atlantic. Yet and still, a few areas of low pressure are beginning to show signs of organizing. One is east of the Bahamas, but westerly winds aloft threaten to disrupt it so there's only a 10% chance it may continue to develop.
The other is a tropical wave a few hundred miles east of the Lesser Antilles. This one has a 20% chance of forming into a tropical depression and possibly a storm. By the way, the next name on the list is Patty. Here are some long range estimates of the location of this wave:
A few of these computer models try to bring the system into the Caribbean, while most expect it will remain in the eastern Caribbean making for a squally weekend there. The waters there are still quite warm and upper-level winds are light, so conditions are favorable for development. I'll update this through the week, so check back here for the latest.
