000 WTPZ41 KNHC 031435 TCDEP1 Tropical Depression Eleven-E Discussion Number 8 NWS National Hurricane Center Miami FL EP112024 900 AM CST Thu Oct 03 2024 The depression continues to produce a large, but poorly organized, area of convection, with the low-level center most likely in the northern portion of the convective mass. Satellite intensity estimates from SAB and TAFB remain 30 kt, and this is the initial intensity for this advisory. The center position has a larger than normal amount of uncertainty, and the initial motion is also a bit uncertain at 045/5. The track forecast guidance suggests a generally northward motion should occur during the next 24-36 h, and the new track forecast follows this in bringing the center to the coast of Mexico in 12-24 hours and inland over the Isthmus of Tehuantepec after that. It is possible that some adjustments to the forecast may occur if data that better shows the center position becomes available. While the environment does not favor significant strengthening before landfall, any intensification at all would bring the system to tropical storm strength, and the new intensity forecast continues to show this occurring. After landfall, the system should quickly weaken, with the remnants eventually becoming absorbed into the large area of disturbed weather that is forming over the western Gulf of Mexico. While the forecast shows the system lasting through 36 h, it could dissipate at any time as it crosses the mountains of Mexico. Regardless of whether intensification occurs, the primary threat remains heavy rainfall that will continue over portions of southern Mexico for the next day or two. KEY MESSAGES: 1. The depression is forecast to become a tropical storm before it reaches the coast of southern Mexico. A Tropical Storm Warning remains in effect for portions of the southern coast of Mexico. 2. Tropical Depression Eleven-E will likely bring heavy rainfall to portions of southern Mexico this week. Flooding and mudslides, especially in areas of steep terrain, are possible, especially across portions of the Mexican states of Chiapas, Oaxaca, Veracruz, Tabasco and coastal Guerrero.
