000 WTPZ42 KNHC 022048 TCDEP2 TROPICAL DEPRESSION TWO-E DISCUSSION NUMBER 1 NWS NATIONAL HURRICANE CENTER MIAMI FL EP022014 200 PM PDT MON JUN 02 2014 The low pressure area located south of the Gulf of Tehuantepec has acquired enough organized deep convection to be classified as a tropical depression. The initial intensity is set at 25 kt, which is based Dvorak classifications from TAFB and SAB, and a ship observation within the eastern portion of the circulation. Environmental conditions, consisting of low vertical wind shear and warm sea surface temperatures, favor intensification during the next few days. The primary limiting factors are likely to be the large and sprawling structure of the cyclone and interaction with land later in the forecast period. The somewhat uncertain initial motion estimate is 330 degrees at 3 kt. The depression is forecast to move slowly northwestward to northward between a mid to upper-level ridge over the west-central Caribbean Sea and a mid- to upper-level trough extending southwestward across the western Gulf of Mexico. While most of the global models agree on a general northwestward to northward motion during the next several days, there are large differences in the forward speed of the cyclone, and how soon the center nears the coast in the model predictions. The GFS shows a faster motion and brings the cyclone to the coast within 2 to 3 days. On the other hand, the ECMWF keeps the depression offshore for more than 5 days. The NHC forecast generally lies between these scenarios and shows a slow motion toward the coast of the Gulf of Tehuantepec. Due to the high amount of uncertainty on the timing of the approach to southern Mexico, a tropical storm watch has been issued for a portion of the coast of southeastern Mexico.
