Darby is an elliptical low-level swirl devoid of persistent deep convection. All 3 satellite agencies considered the system too weak to classify. A combination of moderate shear and cooler waters along the expected track of the feature makes regeneration unlikely. Thus, the system is being declared a post-tropical remnant low with this advisory. The remnants of Darby are expected to become a trough which should continue tracking toward the west-northwest toward a weakness in the subtropical ridge over the next couple of days.
This will be the last advisory issued by the Central Pacific Hurricane Center on Darby unless regeneration occurs. Additional information on this system can be found in the High Seas Forecasts issued by the National Weather Service in Honolulu under AWIPS header HFOHSFNP and WMO header FZPN40 PHFO.
