Here is the latest on TS Don, as of 4:00pm CDT:
ABOUT 425 MI…690 KM ESE OF CORPUS CHRISTI TEXAS
ABOUT 395 MI…635 KM E OF BROWNSVILLE TEXAS
MAXIMUM SUSTAINED WINDS…45 MPH…75 KM/H
PRESENT MOVEMENT…NW OR 305 DEGREES AT 16 MPH…26 KM/H
MINIMUM CENTRAL PRESSURE…1005 MB…29.68 INCHES
Little change from my last update at 1 pm.
Max sustained winds are still holding at 45 mph (40 knots). Looking at water vapor imagery, Tropical Storm Don continues to move into drier air. This and a little bit of shear may be the only things stopping Don from becoming a stronger tropical storm. Some dynamical computer forecasting models are still having trouble developing this system into a tropical storm, even on their latest runs. GFS finally recognized this system as a tropical storm on its 12Z run this morning. CMC, GFS, and UKMET all have this system making landfall a little further south than what the tropical forecast models have. In fact, most of the dynamical computer models do.
The National Hurricane Center has said in their 4:00pm CDT update discussion that they may have to adjust the forecast track a little further south for their next update. For now, here is their forecast track:
