At 2 a.m., the center of Tropical Storm Hanna was located just offshore near latitude 33.3 north, longitude 78.8 west or about 30 miles south of Myrtle Beach, S.C. and about 60 miles southwest of Wilmington, N.C.
Hanna is moving toward the north-northeast near 21 mph. This motion is expected to continue during the next several hours with a gradual turn to the northeast and an increase in forward speed today and tomorrow. On the forecast track, the center of Hanna will make landfall near the border between South Carolina and North Carolina within the next couple of hours, then move across eastern North Carolina later this morning, along the mid-Atlantic coast later today and tonight, and along the coast of the northeastern United States and southeastern Canada on Sunday.
Maximum sustained winds are near 70 mph, with higher gusts. Although no significant change in strength is forecast before landfall of the center in south or North Carolina, it would only take a small increase in wind speed for Hanna to become a hurricane. Weakening is expected after landfall and Hanna should become an extratropical storm by early Sunday.
Tropical storm force winds extend outward up to 260 miles, mainly to the north and east of the center.
The latest minimum central pressure reported by an Air Force reconnaissance aircraft was 983 mb or 29.03 inches.
Coastal storm surge flooding of 3 to 5 feet above normal tide levels, along with large and dangerous battering waves, can be expected near and to the east of the path of the center of Hanna.
Hanna is expected to produce rainfall accumulations of 3 to 7 inches from coastal South Carolina northward through central and eastern North Carolina into the mid-Atlantic states, with isolated maximum amounts of 10 inches possible. The potential for flash flooding will be significant for the mid-Atlantic region and southern New England.
Isolated tornadoes are possible over the coastal plains of South and North Carolina and southeast Virginia this morning.
The next advisory will be issued by the National Hurricane Center at 5 a.m. EDT.
