Hector is expected to weaken over cooler water before its center passes within 200 miles of the Big Island later this week, according to AccuWeather, though the island's southern tip is included in the NHC's five-day storm forecast cone.
There are no coastal watches or warnings in effect but the center said the Hawaiian Islands should monitor the hurricane's progress. Kilauea's latest volcanic event began more than three months ago, sending destructive currents of lava into neighborhoods on the island's southeast side.
Hurricane Hector strengthened to a Category 4 storm Saturday as it churned toward the Central Pacific.

"A motion toward the west-northwest at an increased forward speed is expected through Tuesday, followed by a westward motion Tuesday night through Friday", weather officials said in a bulletin.
It unclear whether it'll hit or just brush the southern edge of the Big Island by Wednesday, the National Weather Service said. We introduced some elevated precipitation chances over the eastern slopes of the Big Island from Wednesday into Thursday as deep tropical moisture will likely move up the slopes of Maunakea and Maunaloa producing enhanced rainfall activity.
Scientists differ over how hurricanes and volcanoes might interact, including the question of whether low atmospheric pressure could help trigger an eruption.
CNN meteorologist Haley Brink said while Hector is heading in Big Island 's general direction, it's too early to tell if it's on a collision course with the volcano.
