The National Hurricane Center is monitoring three areas of disturbed weather across the Atlantic Ocean for possible tropical development, but none of the systems pose a direct threat to Florida. Despite the appearance of a ramp up of tropical activity, conditions still remain unfavorable for significant development from any of the three systems. None of the major computer forecast models show significant development of the feature, and it is expected to remain only a marine interest. NHC forecasters have given the disturbance a medium chance of development as it moves into the central Atlantic. Roughly two-thirds of all Atlantic tropical cyclone activity occurs between Aug. 20 and Oct. 10 when sea surface temperatures across the Northern Hemisphere are at their warmest levels of the year.
