Tropical Depression Fourteen-E Forecast Discussion Number 1
2019-09-17 16:48:08| National Hurricane Center (East Pacific)
Issued at 900 AM MDT Tue Sep 17 2019 000 WTPZ44 KNHC 171448 TCDEP4 Tropical Depression Fourteen-E Discussion Number 1 NWS National Hurricane Center Miami FL EP142019 900 AM MDT Tue Sep 17 2019 Deep convection has intensified over the small area of low pressure that NHC has been monitoring for several days. Both SAB and TAFB estimates indicate that there is now enough organized thunderstorm activity to initiate advisories on a tropical depression, and the initial wind speed of 30 kt matches the overnight scatterometer data and the subjective Dvorak estimates. The initial motion is an uncertain 335/8 kt, with steering provided by a distant low-level ridge to the east. The cyclone is forecast to gradually turn toward the northwest and west-northwest during the next several days as it runs into the southwestern side of a mid- latitude ridge centered over northwestern Mexico. The biggest complication is Tropical Storm Lorena to the northeast, which some of the model guidance, such as the 6Z GFS, shows a binary interaction with at longer term, which could induce a more northward motion. While I can't rule that out, the forecast will stay closer to the models that show less interaction, such as the more westward HWRF and ECMWF solutions, and the NHC forecast is close to a blend of those models. While almost all of the guidance indicates strengthening of this depression into a hurricane in a few days, this forecast is problematic because of the proximity to Lorena. Convective outflow from Lorena could induce more easterly shear than is currently forecast if the tracks get closer together. For now, since the cyclones are forecast to remain a fair distance from one another, this wind speed prediction assumes that the low-shear environment in most of the models materializes, and the forecast follows the corrected-consensus intensity guidance HCCA.
