   Areas affected...Coastal MS...Coastal AL

   Concerning...Severe potential...Tornado Watch likely 

   Valid 071358Z - 071500Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Increasing threat for brief tornadoes expected across
   coastal MS and AL from now into this afternoon.

   DISCUSSION...Recent radar imagery has shown an increase in cellular
   convection along a feeder band arcing from about 15 miles south of
   GPT back further southeastward into the central Gulf of Mexico.
   Additionally, the areas just upstream of these storms has somewhat
   thinner cloud cover, suggesting the potential for modest heating
   once it moves onshore. Based on the limited observations available,
   the area along and south of this feeder band is characterized by
   dewpoints in the mid to upper 70s. These thermodynamic conditions
   underlie strong low-level flow throughout the eastern periphery of
   the tropical cyclone. All of these factors will contribute to
   relatively higher threat for brief tornadoes from now into into the
   afternoon.
