POST-TROPICAL CYCLONE ORLENE DISCUSSION NUMBER  25
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP162016
800 PM PDT FRI SEP 16 2016

Deep organized convection has been absent in Orlene for over 18
hours at this point.  Given the expectation of continued hostile
conditions - cool SSTs and a stable, dry atmosphere - convection is
unlikely to resume and Orlene is now considered a post-tropical
remnant low.  Peak winds are estimated to be about 30 kt, assuming
a continued spin down of the circulation.  The system should
gradually weaken and open up into a trough in about three days.

Orlene is moving toward the west at about 8 kt.  The remnant low
should advect along in the low-level trade wind flow at a somewhat
faster forward speed until dissipation.
