   Areas affected...Portions of north FL...far southern AL...far
   southern GA

   Concerning...Tornado Watch 20...

   Valid 221516Z - 221615Z

   The severe weather threat for Tornado Watch 20 continues.

   SUMMARY...Through 16Z, the severe risk will remain concentrated
   within a zone extending around 90 miles north of the FL/AL Gulf
   coast eastward to the Atlantic.

   DISCUSSION...Through 16Z, bands and clusters of sustained storms
   will continue within the aforementioned corridor. An MCS/storm
   cluster across far south-central/southeastern GA will continue to
   edge toward northeast FL -- affecting areas generally north of
   Jacksonville. Damaging winds will be the primary concern with this
   more linear-oriented convection. Warm-advection-related convection
   with large hail and perhaps isolated wind-damage potential will
   continue westward through parts of the central FL Panhandle. Then,
   farther west, areas across the western FL Panhandle and adjacent
   southwest AL are being monitored for increasing potential for
   supercell storms to develop onshore from the Gulf and spread
   east-northeastward. Richer Gulf moisture will continue to be
   advected inland promoting increasing potential for surface-based
   storms, and the tornado potential will be increasing.
