TTAA00 KNHC DDHHMM
Post-Tropical Cyclone Aletta Discussion Number 25
NWS National Hurricane Center Miami FL EP022018
200 PM PDT Mon Jun 11 2018
The depression has degenerated into a remnant low pressure system
due to the lack of any convection during the past 14 hours, and is
mainly a large swirl of cold-air stratocumulus clouds now. The
initial intensity of 30 kt is based on a few 29- to 30-kt wind
vectors noted in recent 1703Z and 1803Z ASCAT overpasses. Further
weakening and gradual spin down of the wind field is expected while
the cyclone moves slowly west-southwestward over sub-26 deg C waters
during the next several days, with dissipation forecast to occur by
day 5, if not sooner.
This is the last advisory on this system issued by the National
Hurricane Center. For additional information on the remnant low
please see High Seas Forecasts issued by the National Weather
Service...under AWIPS header NFDHSFEPI and WMO header FZPN02 KWBC.
