UPDATE: 11 p.m.

Olivia is now a Category 3 hurricane 1,555 miles east of Hilo and 1,730 east of Honolulu.

Meteorologists expect it to weaken as it nears the islands early next week, but it’s uncertain by how much. Forecasters said Olivia will then move through the region from east to west Tuesday night through midweek.

At 11 p.m., Olivia was moving toward the west-northwest near 15 mph.

Maximum sustained winds have decreased to near 125 mph with higher gusts. Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 115 miles.

As Hurricane Norman passes northeast of the state, trades are forecast to trend down through Friday.

“Clouds and showers will favor windward and mauka locations Friday, then shift over the interior and leeward locations each afternoon beginning Saturday,” weather officials said.

The National Weather Service said Norman is moving toward the northwest near 8 mph.

Meteorologists are warning of high surf, but they don’t expect the storm to directly affect the state.

Norman was packing maximum sustained winds near 85 mph, making it a Category 1 hurricane. Wind shear and cooler ocean temperatures are expected to weaken it over the next few days.

Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 105 miles.

5 p.m.

Olivia has strengthened to a Category 4 hurricane and is forecast to approach the islands from the east next week.

Olivia was moving toward the west-northwest near 14 mph this evening. Weather officials said it’s expected continue on this track through Saturday, followed by a gradual turn toward the west.

At about 5 p.m., Olivia was about 1,645 miles east of Hilo and about 1,830 miles east-southeast of Honolulu. Maximum sustained winds are near 130 mph with higher gusts. Hurricane-force winds extend outward up to 30 miles from the center while tropical storm-force winds extend 115 miles.

Under the current forecast, Olivia would enter the Central Pacific over the weekend as a Category 2 storm, with approximate maximum sustained winds of 100 mph. By the end of the current 5-day forecast, it would be a Category 1 storm just a couple hundred miles northeast of Hilo. While it is too soon to know Olivia’s potential impact on Hawaii, forecasters said their confidence in the current 5-day-forecast path is “very high.”

Much closer to Hawaii, Hurricane Norman continues to weaken well east-northeast of Maui as it tracks toward the northwest. Maximum sustained winds are near 100 mph with higher gusts, generating large surf for east-facing shores.

A high surf warning is in effect until 6 a.m. Friday for eastern shores of most islands. Forecasters said a large swell from Norman will peak tonight and gradually decline Friday.

Hurricane-force winds extend up to 30 miles from the center while tropical storm-force winds extend out 105 miles.

Norman is forecast to pass 200 to 300 miles to the northeast of the island chain over the next couple of days. The Central Pacific Hurricane Center said it was moving northwest near 9 mph this evening.

At 5 p.m., Norman was about 275 miles northeast of Hilo and about 405 miles east of Honolulu, forecasters said.

Hawaii County officials said that winds may increase in “localized areas” today, and that all county beach parks on the north and east side of the island, from South Point to Upolu Point, are closed for the day. All permits and reservations for these parks have been cancelled, they added.
