Satellite images, weather maps and tracks of Tropical Storm Josephine 2020, August 9 - 16. Max wind speed 45mph.
The low-level swirl seen in visible satellite imagery has become less defined this afternoon (August 16), and ASCAT surface wind data that arrived shortly after the release of the previous advisory indicated that Josephine had degenerated into a trough of low pressure. As a result, this will be the final NHC advisory on this system. The ASCAT revealed a small area of 30-knot winds along the northeast side of the trough axis, and that will be the initial wind speed for this advisory. The remnants are forecast to continue encountering a hostile upper-level wind environment over the next couple of days and re-generation of the system is not expected during that time. The strong upper-level winds are forecast to decrease later in the week, but it appears that there will not be much left of the system to take advantage of those conditions.
The remnants are moving west-northwestward at 10 knots, and should turn northwestward and northward over the next couple of days as a low- to mid-level trough moves near the southeastern U.S. coast.
This is the last NHC advisory on this system. Future information can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at https://ocean.weather.gov/shtml/NFDHSFAT1.php
