   Areas affected...eastern North Carolina into southeastern Virginia

   Concerning...Tornado Watch 613...

   Valid 081518Z - 081715Z

   The severe weather threat for Tornado Watch 613 continues.

   SUMMARY...Local risk for brief tornadoes will continue, north and
   east of the center of T.S. Debby.

   DISCUSSION...Latest radar loop shows low-topped, occasionally
   rotating convective cells moving northwestward across eastern North
   Carolina, within the northeast quadrant of Debby(now centered over
   northeastern South Carolina).  A lack of inland lightning is
   currently observed, reflecting the weak CAPE within the tropical
   environment revealed by area/morning RAOBs.  With that said, a very
   favorable low-level wind field is also indicated, with flow veering
   and increasing notable with height through the lower portion of the
   troposphere, reaching/exceeding 50 kt from the southeast at 800m to
   1000m AGL.  This is providing a favorable environment for
   occasional, and briefly strong -- low-level spin-ups, and expect
   this trend to continue through the day today.  With WW 613 set to
   expire at 08/17Z, a new tornado watch will be needed, extending
   farther northward to include central Virginia.
