   Concerning...Tornado Watch 402...

   Valid 260823Z - 261030Z

   The severe weather threat for Tornado Watch 402 continues.

   SUMMARY...Tornado threat will continue across south Texas through
   the morning. The primary area of concern will be across far south
   Texas in the vicinity of Brownsville.

   DISCUSSION...The low-level wind field across south Texas will remain
   conducive for at least transient low-level circulations within
   persistent Tropical Storm Hanna convective bands through the
   morning. Recent radar trends have shown an increase in low-level
   rotation associated with a two distinct convective bands: 1) across
   northeast Mexico, immediately south of Brownsville; and 2) over the
   Gulf of Mexico to the east-southeast of Brownsville. Additional
   intense/persistent convective bands exist farther east across the
   western Gulf of Mexico.

   As Hanna continues to slowly move into northern Mexico, these
   convective bands across the far western Gulf of Mexico will continue
   to move onshore. As this occurs, the threat for tornadoes will
   continue through the morning.
