Hurricane Hector is no making its closest pass to the southern tip of the big island of Hawaii where Tropical Storm Warnings are in effect. The land impacts to Hawaii are minimal if any and the hurricane will pass well south of the other islands by well over 200-300 miles. The main impact is to the coastal waters with winds and rough seas until the hurricane moves far enough to the west. Over the next few days Hurricane Hector is likely to cross the International Dateline and become Typhoon Hector when it does so. Weather models actually carry it pretty far to the west recurving east of Japan. We don’t see this happen very often that a hurricane starts in the Eastern Pacific and manages to make it all the way across.
