"Invest 99 in the east Atlantic
This one is likely to develop and a “must watch” for Floridians. Invest 99 was nothing more than a disorganized mess of thunderstorms over the eastern Atlantic on Friday. However, atmospheric and oceanic conditions are favorable for development when it reaches the central Atlantic, and the National Hurricane Center has given it a “high chance” of becoming a tropical storm. Most reliable forecast models, including both the European and American-based GFS, show some resemblance of a tropical weather system near or north of the Leeward Islands about a week from now.
While it certainly too early to project an eventual outcome of Invest 99, this development should serve as a reminder to all Floridians that the heart of the Atlantic hurricane season is approaching. More than half of the season’s annual activity occurs after August 15. The season’s tradition peak (in terms of storm frequency) is around September 10."
