At 500 PM AST (2100 UTC), the center of Tropical Depression Rose was located near latitude 24.2 North, longitude 40.2 West. The depression is moving toward the west northwest near 10 mph (17 km/h). A northwestward motion is expected tonight, with a turn toward the north forecast by Thursday night. A motion toward the northeast is expected on Friday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Gradual weakening is expected during the next couple of days, and Rose is expected to degenerate to a remnant low pressure area on Thursday or Thursday night. The estimated minimum central pressure is 1010 mb (29.83 inches).

Rose is currently comprised of a swirl of low-level clouds, with the only significant convection occurring about 120 n mi southeast of the center. Satellite intensity estimates have decreased, and are now 25 kt from TAFB and too weak to classify from SAB. Based mainly on earlier scatterometer data, the initial intensity is held at a possibly generous 30 kt. Rose remain in an area of northwesterly shear and upper-level convergence, and dry mid-level air has been entraining into the circulation. The large-scale model guidance indicates that the hostile conditions will continue for at least another 36 h, and based on model forecasts of convection Rose is now expected to degenerate into a remnant low pressure area in 24 h or less. It should be noted that the GFS and HWRF models suggest the possibility that convection could re-develop in the 48-96 h period due to the remnant low interacting with an upper-level trough. For now, the intensity forecast will not call for re-generation at that time.

The initial motion is now west-northwestward or 300/9 kt. A northwestward motion is expected for the next 12-24 hours as Rose or its remnants are steered by a mid-level ridge over the eastern Atlantic. After that time, the system is expected to turn northward, northeastward, and eventually east-northeastward as it becomes steered by a deep-layer trough that includes the remnants of Odette. Since Rose has moved a bit to the west of the previous forecast, the guidance and the new forecast track have also shifted westward during the first 36 h. The new NHC track is to the east of the consensus models for the first 36 h, and close to the consensus aids after that time.
