Satellite images and tracking maps of Category 4 Major Hurricane Genevieve 2020, August 14 - 21. Max wind speed 130mph.
Cool waters and less favorable thermodynamic conditions have continued to take a toll on Genevieve. The system has not had any deep convection for more than 12 hours, and it is unlikely that any organized deep convection will return. As a result, Genevieve has become a post-tropical cyclone and this will be the final NHC advisory on this system. The initial wind speed is set at 35 knots, which is in agreement with recent scatterometer data. The post-tropical cyclone should continue to gradually weaken over cooler water during the next couple of days, and the global model guidance indicates that the circulation will become an open trough within 72 hours.
The cyclone continues to move northwestward at about 10 knots. A northwestward motion is forecast to continue over the next couple of days, but the forward speed of the system is expected to slow as it becomes increasing shallow and is steered by the weaker low-level flow. The track guidance remains tightly clustered and the new foreast is an extension of the previous advisory.
This is the final NHC advisory on Genevieve. Additional information on the post-tropical cyclone can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at https://ocean.weather.gov/shtml/NFDHSFEPI.php
