At 500 PM AST (2100 UTC), the center of Tropical Depression Peter was located near latitude 21.7 North, longitude 66.7 West. The depression is moving toward the north northwest near 5 mph (7 km/h). A similar motion with gradual turn to the north is expected tonight followed by a turn toward the north northeast tomorrow. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Gradual weakening is expected during the next couple of days, and Peter is forecast to degenerate into a remnant low tonight or tomorrow. The estimated minimum central pressure is 1008 mb (29.77 inches).

Peter continues to just barely maintain its classification as a tropical cyclone. While the low-level circulation has remained intact today, the convection continues to be located well downshear to the east. However, there have been a few convective elements forming a bit closer to the center recently and that is the primarily justification for maintaining advisories on Peter as a tropical cyclone this afternoon. The initial intensity is maintained at 30 kt given the earlier scatterometer data, though this might be generous. Continued strong southwesterly vertical wind shear within a dry mid-level environment should ultimately strip the remaining convection away from Peter, with the tropical cyclone expected to finally peter out as a post-tropical remnant low in the next 12 hours.

The depression has been moving very slowly recently, with an estimated north-northwestward motion of 340/4 kt. The cyclone is expected to turn northward and then north-northeastward following a weakness in the low-level ridge until the system finally opens up into a trough, sometime in the 48 to 60 hour period.
