Issued at 300 PM MDT Fri Oct 09 2020 157 WTPZ44 KNHC 092034 TCDEP4 Tropical Depression Norbert Discussion Number 17 NWS National Hurricane Center Miami FL EP192020 300 PM MDT Fri Oct 09 2020 Deep convection has persisted near the center of Norbert for the past several hours. However, a recent ASCAT overpass as well as visible satellite imagery revealed that the low-level circulation is becoming elongated. In addition, the wind field surrounding the depression suggests that is remains very near, if not embedded in the Intertropical Convergence Zone (ITCZ). The initial intensity of 25 kt is based off data from the ASCAT overpass. The GFS and ECMWF both indicate that Norbert will open into a trough as it becomes absorbed into the ITCZ in a couple of days, and the official forecast now indicates dissipation just after 48 h. Norbert continues to move toward the northwest at 3 kt. A slow northwestward motion is expected until dissipation as the cyclone is steered by weak mid-level ridging to its northeast. The latest NHC track forecast is little changed from the previous one, and is near the various track consensus guidance.
