A satellite image, supplied by the US National Weather Service, shows Hurricane Hector, a category four, as it moves towards the south of Hawaii.
There was no change in the track forecast reasoning in the 2 p.m. update and Hector is forecast to move westward to west-northwestward during the next day or so to the south of a deep-layer subtropical ridge.
The system is expected to cross into the Central Pacific tonight or early Monday, and cross through the Hawaiʻi region around Wednesday.
Hurricane Hector was swirling harmlessly in the Pacific about 1,700 miles east of Big Island but it grew into a category three hurricane on Friday as its maximum sustained winds reached 120mph.
The National Weather Service and Hawaii County Civil Defense remind residents and visitors it's a good time to ensure they have their hurricane plan in place.
"Slow weakening is forecast during the next few days".
This image shows how far from the center of the storm strong winds may be felt
Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 105 miles.
Hawaii's Big Island already is dealing with another natural disaster - the eruption of Kilauea Volcano in the southeast.
Maximum sustained winds have increased to near 140 miles per hour (220 km/h) with higher gusts.
"Eruptions and lava flows from the volcano have dramatically waned this weekend, so the amount of laze and vog being produced is significantly less than earlier this summer", Andrews said.
Hurricane Hector roared through the Central Pacific on Sunday and is expected to pass near the Big Island of Hawaii, where a volcano continues to send lava into the sea.
Since the Kilauea volcano erupted in May on the Big Island, thousands of residents have been displaced, hundreds of homes destroyed and roads damaged.
