Areas affected...coastal Georgia through northeast and central
Florida

Concerning...Tornado Watch 51...

Valid 151830Z - 152000Z

The severe weather threat for Tornado Watch 51 continues.

SUMMARY...Threat for primarily isolated damaging wind gusts and a
couple of tornadoes will persist across central through northeast FL
next couple of hours. Line of storms and a couple of discrete cells
are approaching the GA coast and will continue to pose a severe
threat before they move offshore by 20Z.

DISCUSSION...Lines of storms continues from coastal GA through
central FL. The overall tendency has been for the southern portion
of the line to weaken as it approaches the western FL coast.
However, some strengthening of the low-mid level winds have been
observed on the Tampa VAD wind profile and the downstream atmosphere
remains moderately unstable. Additional storms have developed east
of ongoing line along an inland convergence zone, and some storm
mergers are likely during the next hour or two which could enhance
downburst potential. Farther north an MCV moving through southeast
GA may be enhancing the the mesoscale environment there where a
couple of discrete cells have shown some increase in intensity.
