DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Storm Fred was located near latitude 31.7 North, longitude 85.2 West. Fred is moving toward the north near 13 mph (20 km/h), and this general motion is forecast to continue early this morning. A motion toward the north-northeast with an increase in forward speed is expected to begin by late morning and continue for the next day or so. On the forecast track, the center of Fred will move across western and northern Georgia today, across the southern Appalachian Mountains tonight, and into the central Appalachians by early Wednesday. NOAA Doppler weather radar data indicate that maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Weakening is expected, and Fred should become a tropical depression later this morning. Tropical-storm-force winds extend outward up to 45 miles (75 km), mainly to the northeast of the center. The estimated minimum central pressure based on nearby surface observations is 1004 mb (29.65 inches).
