DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Tropical Storm Helene was located near latitude 32.8 North, longitude 83.0 West. Helene is moving toward the north near 30 mph (48 km/h). A turn toward the north is expected this morning, taking the center over central and northeastern Georgia. After that, Helene is expected to turn northwestward and slow down over the Tennessee Valley later today and Saturday.
Maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. Continued weakening is expected, and Helene is expected to become a post-tropical low this afternoon or tonight. However, the fast forward speed will allow strong, damaging winds, especially in gusts, to penetrate well inland across the southeastern United States, including over the higher terrain of the southern Appalachians.
Tropical-storm-force winds extend outward up to 275 miles (445 km) mainly to the east of the center. The Marine Corp Air Station at Beaufort, South Carolina, recently reported a wind gust of 75 mph (120 km/h).
The minimum central pressure based on surface observations is 968 mb (28.59 inches).
