Disturbance in the Central Atlantic......
Take note of the ragged cut-off & bad data over the far E. Atlantic. The problem is that the GOES-13 satellite is malfunctioning. Work is ongoing but for the time being the satellite -- GOES-15 -- that usually covers the Western U.S. & parts of the Pacific has been moved east to cover more of the Atlantic Basin.

A disturbance -- combination of an upper low & tropical wave -- is in the Central Atlantic some 1,000 miles east of Puerto Rico. The system will slowly move northwest & should turn north in the long run. Some slow development is possible, but the disturbance should stay well east of the U.S.
Long range forecast models continue to show possible tropical development in or near the Caribbean next week. This is a climatologically favored region for late season development, so it's an area to watch. Strong upper level troughing looks like it'll remain in place -- in one form another -- over the Eastern U.S. which could protect the Southeast U.S. from any Caribbean disturbance but will ultimately depend on the exact orientation & intensity of the trough.
