TROUGH. WITH WIDESPREAD CLOUDS AND PRECIPITATION ACROSS THIS
REGION...POTENTIAL FOR DESTABILIZATION APPEARS TO BE QUITE LIMITED.
THEREFORE...DESPITE MODERATELY-STRONG DEEP-LAYER FLOW ACROSS THE

FORECAST TO MOVE EWD/SEWD ACROSS THE FL PENINSULA THROUGH THE

IMMEDIATE COASTS OF SERN GA AND THE CAROLINAS...TO ACCOUNT FOR THE
POSSIBILITY THAT HIGHER THETA-E GULF STREAM AIRMASS NEAR THE COAST

SURFACE-BASED STORM DEVELOPMENT SHOULD REMAIN OFFSHORE.
