Issued at 800 AM PDT Sat Aug 03 2019 000 WTPZ43 KNHC 031512 TCDEP3 Tropical Depression Eight-E Discussion Number 1 NWS National Hurricane Center Miami FL EP082019 800 AM PDT Sat Aug 03 2019 First light visible satellite images indicate that the disturbance over the open eastern Pacific has developed a well-defined center just west of an area of concentrated deep convection. Based on this, advisories have been initiated for Tropical Depression Eight-E. An earlier scatterometer pass measured winds of about 30 kt, and this is the basis for the initial intensity. Vertical shear of 20-25 kt that is currently displacing convection off to the east of the low-level center is forecast to continue for the next few days as the system moves under the base of a mid- to upper-level trough. This shear is expected to prevent any strengthening of the cyclone in the near term. In addition to the shear, the depression will move into a drier airmass and begin to move over more marginal SSTs in about 24 hours. This should result in weakening and the depression is expected to dissipate in a couple of days. Although the depression is currently moving west-northwestward at about 9 kt, all of the global models forecast that it will turn westward later today, steered primarily by low-level easterly winds. The cyclone should then continue westward for the next day or two until it dissipates.
