   Areas affected...the western Florida Panhandle

   Concerning...Tornado Watch 490...

   Valid 160409Z - 160615Z

   The severe weather threat for Tornado Watch 490 continues.

   SUMMARY...The greatest threat for a couple of tornadoes will persist
   along the coast of western Florida Panhandle through 08Z.

   DISCUSSION...The center of hurricane Sally remains just offshore of
   the AL coast and is moving very slowly north northeast at 2 miles
   per hour. See latest discussion from NHC for more details on Sally.
   The more unstable portion of the warm sector remains just offshore
   where dewpoints are in the upper 70s F. As the center of Sally
   continues northward tonight into the early morning, the richer
   moisture will advect inland as low-level trajectories become more
   southeasterly to the south of a warm front currently located near
   the coast. Discrete, shallow convection persists in a couple of
   outer rainbands east of the center. Some of these cells continue to
   exhibit updraft rotation as they move onshore. The best tornado
   threat exists in a small corridor near the coast as mini-supercells
   interact with the warm front before weakening as they move into the
   more stable air farther inland.
