Watches and warnings NHC, verbatim

A Hurricane Warning is in effect for...
* Kauai County, including the islands of Kauai and Niihau
* The Papahanaumokuakea Marine National Monument from Nihoa to French Frigate Shoals
A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Interests elsewhere in the Hawaiian Islands and the Papahanaumokuakea Marine National Monument should monitor the progress of Lowell. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office.
