Satellite imagery, surface observations, and radar data indicate
that the main vorticity center of the disturbance has moved inland
over northeastern Mexico and the associated convection has
decreased.  Based on this, the chance for development has ended and
the coastal warnings are being discontinued.  Therefore, this will
be the last NHC advisory on this system.  Additional information on
this system can be found in statements from local Weather Forecast
Offices in the United States and from the Meteorological Service of
Mexico.

The disturbance should move north-northwestward for the next 12 h
or so before it becomes absorbed in a larger weather system
developing over Texas.


KEY MESSAGES:

1. Locally gusty winds may occur in squalls over portions of
northeastern Mexico and southern Texas tonight.

2. Rain from the disturbance should affect the northeastern coast
of Mexico across the state of Tamaulipas tonight and Sunday. This
rainfall could produce isolated flash flooding. The system could
also produce isolated moderate to heavy rainfall across portions of
South Texas, but significant flooding impacts are not expected
there.
