   The severe weather threat for Tornado Watch 686, 687 continues.

   SUMMARY...A tornado threat will continue tonight from eastern
   Georgia into South Carolina and southern North Carolina.

   DISCUSSION...Tropical Storm Helene is currently moving northward
   through east-central Georgia. Mosaic radar imagery shows that
   rainbands extend outward up to 200 statute miles to the north of
   Helene. Within these rainbands, several discrete cells are ongoing
   across eastern South Carolina, where the tornado threat is maximized
   at this time. The WSR-88D VWP at Wilmington, North Carolina appears
   representative of the environment from the middle South Carolina
   coast northward to Wilmington, and has 0-6 km shear near 50 knots
   with 0-3 km storm-relative helicity in the 400 to 500 m2/s2 range.
   This will continue to support a tornado threat as thunderstorms move
   north-northwestward across South Carolina over the next several
   hours. The tornado threat should gradually move northward into
   southern and central North Carolina.
