DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Depression Claudette was located near latitude 32.9 North, longitude 86.7 West. The depression is moving toward the northeast near 13 mph (20 km/h). A turn toward the east-northeast is expected later today. On the forecast track, the system should cross portions of the southeast U.S. through Sunday night, and move over the coasts of the Carolinas into the western Atlantic Ocean on Monday. Maximum sustained winds remain near 30 mph (45 km/h) with higher gusts. These winds are mainly occurring over the Gulf of Mexico well to the south of the center. Little change in strength is expected today. However, the cyclone is forecast to become a tropical storm again when it moves across the Carolinas Sunday night or early Monday. The estimated minimum central pressure based on surface observations is 1006 mb (29.71 inches).
