Hanna nearing landfall...

Just in time for landfall, Hanna is getting organized, and has very strong centralized convection now.  The center is located about 140 miles southeast of Charleston as of 7pm EDT (23Z) and tracking north at 17kts.  At this rate, it should be making landfall somewhere between Myrtle Beach SC and Wilmington NC in about 6 hours (1am local time).

Given the current satellite and radar presentation, it could become a hurricane prior to landfall.

Another important consideration is that the storm has a large wind field, so being right under the center doesn't matter so much.  Tropical Storm Warnings and Watches cover the eastern coast from Georgia up to New Hampshire now.... while Hurricane Watches cover SC and NC.
