838 WTNT44 KNHC 210235 TCDAT4 Potential Tropical Cyclone Four Discussion Number 6 NWS National Hurricane Center Miami FL AL042022 1000 PM CDT Sat Aug 20 2022 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.
