Disaster Warning

The National Weather Service Central Pacific Hurricane Center will help you keep track of the weather and provide weather and disaster warnings (if any) before you reach an island in Hawaii. The Hawaii Department of Defense provides early warning with a statewide Forecast and Warning program with sirens.
