000 WTPZ41 KNHC 041449 TCDEP1 Tropical Depression One-E Discussion Number 1 NWS National Hurricane Center Miami FL EP012024 900 AM CST Thu Jul 04 2024 Showers and thunderstorms have become better organized over the past 12-18 hours in association with the small area of low pressure that NHC has been monitoring for the past several days. There have been no recent scatterometer or passive microwave passes to assess the low-level circulation of the system. However, the persistence of the convection and the current satellite structure suggest a well-defined surface circulation has likely formed underneath the colder cloud tops. It is determined that the first tropical depression of the eastern Pacific season has formed. The initial intensity is set at 30 kt based on a T2.0 subjective Dvorak classification from TAFB. The center position of the depression is uncertain based on the lack of data, but the initial estimated motion is northwest (325/8 kt). The models agree that this motion will continue into tonight, followed by a westward turn on Friday within the low-level flow. With warm SSTs and relatively low shear today, it is possible that the system could briefly strengthen into a tropical storm, though not explicitly forecast. The tropical cyclone will move across the 26C isotherm during the next 24-36 h, and the cooler waters and drier mid-level environment thereafter should induce a weakening trend. In fact, the GFS and ECMWF model-simulated satellite imagery suggest convection is likely to collapse on Friday, and the system is forecast to become a remnant low by Friday night and dissipate later this weekend.
