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.
