Tropical Depression Fourteen-E Forecast Discussion Number 1

Issued at 800 AM PDT Wed Aug 26 2020 000 WTPZ44 KNHC 261445 TCDEP4 Tropical Depression Fourteen-E Discussion Number 1 NWS National Hurricane Center Miami FL EP142020 800 AM PDT Wed Aug 26 2020 Earlier scatterometer data and GOES-16 Proxy-VIS satellite imagery indicate that the area of low pressure located several hundred miles southwest of the southern tip of the Baja California peninsula has acquired sufficient convective organization and a well-defined surface circulation, and is now classified as a tropical cyclone. Dvorak satellite intensity estimates and the aforementioned scatterometer data support an initial wind speed of 30 kt for this advisory. Moderate to strong east-northeasterly shear, the same inhibiting upper wind pattern that is affecting depression Thirteen-E, is forecast to hamper significant development through the entire forecast period. Therefore, only modest strengthening in the next 24 hours is expected, which agrees with the statistical- dynamical guidance and the large-scale models. The depression is moving rather slowly toward the northeast, or 040/2 kt. The low to mid-level steering synoptic pattern consists of a cyclonic gyre stretching southwestward from Hurricane Laura over central Mexico and into the eastern Pacific. This feature should cause the depression to continue in a northeastward general direction at a relatively slow pace through Friday. Afterward, a gradual turn toward the north-northwest and west-northwest is expected as high pressure currently over the southwestern U.S. builds westward over the Baja California peninsula and adjacent eastern Pacific. The NHC official forecast is a reflection of a blend of the HCCA and TVCE consensus aids.
