Surf along east facing shores is building and is expected to peak tonight and into early Wednesday at 12 to 15 feet for the Big Island and 6 to 10 feet for Maui County.
Emergency Management officials are still warning Hawaii Island residents to be aware of possible high wind, flooding rain, and high surf.
"Hector is expected to pass far enough to the south so that no important wind issues are expected to impact the Big Island", AccuWeather Hurricane Expert Dan Kottlowski said. "The strongest winds are expected down the slope of the mountains, across elevated terrain, over headlands, and through gaps".
Swells generated by Hector will bring large and unsafe surf to portions of the main Hawaiian islands through tonight.More news: Barcelona name Lionel Messi new captain to replace Andres Iniesta
