Tropical Depression Joyce Forecast Discussion Number 25
2018-09-18 22:29:32| National Hurricane Center (Atlantic)
Issued at 500 PM AST Tue Sep 18 2018 812 WTNT45 KNHC 182029 TCDAT5 Tropical Depression Joyce Discussion Number 25 NWS National Hurricane Center Miami FL AL102018 Issued by the NWS Weather Prediction Center College Park MD 500 PM AST Tue Sep 18 2018 Deep convection has generally been on the wane during the past day or so near the center of Joyce, and it is getting very close to no longer having organized deep convection. With the decrease in overall organization, the initial wind speed is set to 25 kt. An environment of strong westerly vertical wind shear (30-40 kt) and marginal sea surface temperatures (around 25C) should cause Joyce to become a remnant low by late tonight or early Wednesday. This agrees well with the latest global model guidance, and the timing of remnant low status has been moved up to 12 hours (or less). The initial motion of Joyce continues to turn and is now south- southwestward (205 degrees at 6 kt). The depression is forecast to turn increasingly to the southwest and west as the central Atlantic ridge builds to the north. Model guidance, except the HWRF, is tightly clustered, so the new forecast track is essentially an update of the previous one, closest to the HCCA consensus model.
