Key Points
1. Regardless of development, the greatest threat to Mexico is flooding from heavy rainfall.
2. We expect Disturbance 3 to make landfall near or just north of Tampico on Tuesday.
3. Strong wind shear will keep the threat very low for Texas. The only impact to Texas from the system will be heavy rainfall.

Our Forecast
Disturbance 3 remains a poorly organized area of low pressure and has not changed in organization over the past few hours. The system will likely develop into a tropical depression and could become a tropical storm before reaching the coast of Mexico near Tampico on Tuesday. After moving inland, the system will weaken rapidly. In the unlikely event that the system were to remain offshore and move toward Texas, strong westerly wind shear would likely cause the system to dissipate before making landfall.

Disturbance 3 will continue to track slowly towards the west-northwest into early Monday before turning more to the northwest during the day Monday. The northwest motion should continue until the system dissipates over northeastern Mexico Tuesday night. Afterward, the remnants of the system will likely move across southern Texas.

Since the system is not forecast to be any stronger than a minimal tropical storm, the greatest threat will be flooding from heavy rainfall. This threat will occur regardless as to whether or not the system develops into a depression or a tropical storm. Some of the rainfall will likely spread northward into Texas late Tuesday through Thursday.

Expected Impacts Onshore
Northeast Mexico – Tampico Area: Isolated power outages may occur due to strong winds. Widespread street flooding is expected. Some flood damage may occur, especially in areas that experience mudslides.

Deep South Texas: Brief travel delays may occur due to urban and small stream flooding.

Expected Impacts Offshore
Bay of Campeche to Offshore Tampico, MX: Scattered squalls will produce wind gusts up to 50 mph and locally rough seas.

Our next advisory will be issued by 3 AM CDT.

The yellow cone represents track error from the previous five years. Over the past five tropical cyclone seasons, the center of the storm tracked within the yellow cone 75% of the time. The cone does not represent the forecast uncertainty in the current advisory for this storm. In addition, strong winds, very high tides, large waves, and heavy rainfall can often extend well outside the yellow cone.
