No persistent deep convection is associated with the low level 
circulation center, with only intermittent deep convection noted in 
the lingering convergent bands well to the east. Thus, the system 
is being declared as a post tropical remnant low. An ASCAT-C pass 
at 1910 UTC indicated an area of 30 kt winds remaining to the north 
of the remnant circulation center, in an area devoid of new deep 
convection. The depression has succumbed to a combination of 
moderately strong shear earlier and, more recently, dry air 
intrusion. The remnant low should continue to move generally toward 
the west in the low-level trade wind flow until it dissipates.

This is the last advisory issued by the Central Pacific Hurricane 
Center on this system. Additional information can be found in the 
High Seas Forecast issued by the National Weather Service in 
Honolulu under AWIPS header HFOHSFNP and WMO header FZPN40 PHFO.
