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.
According to the latest update, Hector was about 1,525 miles east of Hilo.
Hurricane Hector maintained strength as a powerful Category 3 storm in the Eastern Pacific overnight as it continued moving closer to the Central Pacific.
The storm had maximum sustained winds of 125 miles per hour and was moving west at 12 miles per hour.
Scientists differ over how hurricanes and volcanoes might interact, including the question of whether low atmospheric pressure from a major cyclone could help trigger an eruption, and much remains unknown on the subject.
Hurricane-force winds extend outward up to 25 miles from the center, and tropical-storm-force winds extend outward up to 80 miles.

The swift vaccinations of more than 3,300 people helped in containing the previous outbreak, which saw 33 deaths. Ebola is a constant threat in the Democratic Republic of Congo as the virus thrives in heavily forested areas.
Hector is about 1360 miles (2190 kilometers) east of South Point, Hawaii, and is forecast to cross into the central Pacific by Sunday night or early Monday. Forecast models have Hector passing to the south of the Hawaiian islands between Wednesday and Thursday, according to KHON.
The forecast track for Hurricane Hector.
"This is a good time for everyone in the Hawaiian Islands to ensure they have their hurricane plan in place".
Lava fragments falling from lava fountains at fissure 8 are building a cinder-and-spatter cone around the erupting vent, with the bulk of the fragments falling on the downwind side of the cone as it continues to feed a channelized lava flow that reaches the ocean at Kapoho during ongoing eruptions of the Kilauea Volcano in Hawaii, U.S. June 11, 2018. Hector is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.
An estimated 700 homes have been destroyed by the volcano, more than 500 of those in just two days, and thousands of people have been displaced.
