The most robust tropical wave of the season is working its way westward through the southern Atlantic Ocean around 10 degrees latitude. It is located about 1200 miles southeastward of the Windward Islands. Satellite images have looked pretty impressive early Wednesday morning and it looks like within the next 24 hours it will be upgraded to Tropical Depression #3.
Forecast computer models track Invest area 93-L (as it is known at this point) north of the islands and towards the Bahamas by early next week. There is a fair amount of dry air several hundred miles ahead of it and lots of dry Saharan dust to the north of it. But if this system can survive and get north of the islands this weekend, the weather pattern close to the east coast of the U.S. will be conducive to support a tropical system.
So at this point, I'd plan on a tropical system of some strength passing between Hatteras and Bermuda the middle of next week. Be sure to check back often as we continue to track the progress of this system.
