.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
A weak east flow will prevail tonight into Wednesday with low
seas. The weather after Wednesday will be dependent upon a
tropical wave currently located over the Yucatan Peninsula...and
has the potential to develop into a tropical storm again as it
moves into the southwest Gulf of Mexico and Bay of Campeche
tonight and Wednesday. The system is now expected to move to the
northwest toward the Lower or Middle Texas coast by early Friday
morning. The chance for rain and strong wind will increase
significantly Thursday and Friday as this potential tropical
system moves toward the northwest. There remains significant
uncertainty regarding the location and strength of this system.
Mariners are advised to monitor the latest forecasts from the
National Hurricane Center.
