   Concerning...Tornado Watch 413...

   Valid 040003Z - 040200Z

   The severe weather threat for Tornado Watch 413 continues.

   SUMMARY...The tornado threat will increase along the coasts of
   eastern South Carolina and eastern North Carolina early this
   evening. As the tornado threat moves northward over the next couple
   of hours, tornado watch issuance will be needed across parts of
   eastern North Carolina.

   DISCUSSION...The National Hurricane Center currently places Tropical
   Storm Isaias about 60 statute miles east of Charleston, South
   Carolina. Isaias is forecast to become a Hurricane and make landfall
   near Wilmington, North Carolina later evening. A distinct band of
   heavy rainfall surrounds the center of Isaias and is affecting
   southern North Carolina and eastern South Carolina at this time. The
   band in far southern North Carolina consists of several discrete
   thunderstorms from the Wilmington area extending offshore about 100
   statute miles. The latest WSR-88D VWP from Morehead City, North
   Carolina shows east-southeasterly surface winds veering to the
   south-southeast at 2 km above ground-level. This is creating strong
   low-level shear with 0-3 km storm relative helicities around 200
   m2/s2. As the strong winds associated with Isaias move northward,
   low-level shear will increase. This will make conditions
   increasingly favorable for tornadoes from far eastern South Carolina
   into eastern North Carolina.
