POST-TROPICAL CYCLONE ROSLYN DISCUSSION NUMBER  17
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP182016
800 AM PDT THU SEP 29 2016

Roslyn has been devoid of deep convection overnight, and the system
consists of only a swirl of low clouds.  Given the lack of
convection, Roslyn has become a post-tropical remnant low.  The
initial intensity is kept at 25 kt based on continuity from earlier
scatterometer data.  The cyclone should spin down over cool waters
and completely dissipate after 24 hours.

The motion is north-northwestward or 345/6 kt.  A weak low-level
ridge to the north and northwest of the system should cause a turn
toward the northwest and west-northwest until dissipation.

This is the last advisory on Roslyn.  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.
