Issued at 800 AM PDT Tue Sep 19 2017 000 WTPZ45 KNHC 191433 TCDEP5 Post-Tropical Cyclone Otis Discussion Number 32 NWS National Hurricane Center Miami FL EP152017 800 AM PDT Tue Sep 19 2017 Otis has been devoid of deep convection for about 10 hours, and the cyclone only consists of a compact swirl of low-level clouds. Therefore, Otis is now classified as a remnant low, and this is last advisory issued by the National Hurricane Center. ASCAT data from last night indicated that maximum winds were near 35 kt. Assuming some spin down since that time due to the loss of deep convection, the initial wind speed is lowered to 30 kt. Continued weakening due to cool SSTs and dry air is expected, and Otis is expected to dissipate in a day or so. The remnant low has turned to the west in the low-level trade wind flow. A west to west-southwest motion is expected until the system dissipates. For additional information on the remnant low please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFEPI.shtml.
