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.
