Below is a Situation Overview provided by the Central Pacific Hurricane Center with details on onset of wind, rain and surf.

“The onset of damaging tropical-storm-force winds on the Big Island could start later this evening, with dangerous hurricane force winds starting in the overnight hours. In Maui County, damaging winds could begin as early as Thursday afternoon, with dangerous hurricane force winds possible starting on Thursday night. On Oʻahu, damaging winds could begin as early as Thursday evening, with dangerous hurricane force winds possible by Friday morning. Hurricane Warnings may need to be expanded to include other islands as Lane draws closer.

“Bands of intense showers and thunderstorms surrounding Lane will begin to spread across the state from the southeast towards the northwest, reaching the Big Island later this morning. Excessive rainfall is possible which could lead to deadly flash flooding, landslides and mudslides. Flooding can occur even in areas not usually prone to flooding. Storm total rainfall amounts greater than 20 inches are possible.

“Swell generated by Lane will produce very large and rough surf, with dangerous rip currents along south, southeast and southwest facing shores.

“Tornadoes and large waterspouts will be possible associated with Lane, mainly along and to the right of the track of the hurricane.”
