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.
