Tropical Depression Eleven-E Forecast Discussion Number 2
2024-10-02 04:34:43| National Hurricane Center (East Pacific)
Issued at 900 PM CST Tue Oct 01 2024 000 WTPZ41 KNHC 020234 TCDEP1 Tropical Depression Eleven-E Discussion Number 2 NWS National Hurricane Center Miami FL EP112024 900 PM CST Tue Oct 01 2024 The depression has not become better organized this evening. Deep convection has been separating from the low-level center, which is now exposed to the east of the thunderstorms. The initial intensity is held at 30 kt, near the high end of the satellite estimates. The system is close to the coast, currently over the Gulf of Tehuantepec, and appears to be moving northward at about 5 kt. The models don't have a good handle on this system, likely because it is weak and relatively small. The official track forecast continues to lean heavily on the ECMWF solution, taking the system inland over southern Mexico on Wednesday. There could be a little strengthening before the depression reaches the coast, but given its current structure, significant intensification is not expected. The main impact from the system is expected to be heavy rainfall, which could lead to flooding and mudslides over portions of southern Mexico and western Guatemala. KEY MESSAGES: 1. The depression is forecast to become a tropical storm before it moves inland over southern or southeastern Mexico on Wednesday. A Tropical Storm Warning remains in effect for that area. 2. Tropical Depression Eleven-E will likely bring heavy rainfall to portions of southern Mexico and Guatemala this week. Flooding and mudslides, especially in areas of steep terrain, are possible, especially from western Guatemala into portions of the Mexican states of Chiapas, Oaxaca, Veracruz, and Tabasco.
