   Areas affected...coastal southeastern South Carolina

   Concerning...Tornado Watch 599...

   Valid 060335Z - 060500Z

   The severe weather threat for Tornado Watch 599 continues.

   SUMMARY...Tornado risk continues in the northeastern quadrant of
   Debby, as the center of the storm lingers over southeastern Georgia.
   With Tornado Watch 599 set to expire at 06/05Z, a new WW will likely
   be required.

   DISCUSSION...Latest radar loop continues to show cellular convection
   within a persistent band situated within the northeastern quadrant
   of Debby's circulation.  Stronger offshore cells continue to exhibit
   compact/occasionally strong circulations, with a couple of tornadoes
   reported onshore over the past 1 to 2 hours.  

   At this time, it appears that this trend may continue, extending
   beyond the scheduled expiration of the existing Tornado Watch (599).
   Given the persistence of a moist/low-CAPE environment combined with
   very strong low-level shear (weakly veering flow with height,
   increasing rapidly to 50 kt at around 800m AGL), which should
   support a continued tornado risk locally, a new watch will likely be
   required, to cover the ongoing threat.
