UPDATE: Monday 4:45 a.m.

Although a statewide high wind warning has been canceled, a high surf warning is in effect for all islands along with scattered weather warnings and advisories as the low-pressure system passes north of Hawaii island this morning.

A high wind warning, however, has been posted for Big Isle summits as National Weather Service officials forecast westerly winds of 90 to 120 mph with gusts up to 150 mph this morning, decreasing to 50 to 70 mph with gusts to 85 mph by late afternoon today. The warning is in effect through 6 p.m.

A wind advisory is in effect for the rest of the Big Island, except for the west side, until noon today. Northwesterly winds of 20 to 35 mph with gusts up to 55 mph are expected over interior and eastern sections, weather officials say.

“Winds will be strongest over and downslope from the higher terrain, and where most efficiently funneled around the terrain and through valleys,” the NWS said in its advisory. “This includes the city of Hilo where strong north to northwest winds are expected briefly during the morning hours.”

The north-facing shores of the Big Island should brace for surf of 15 to 25 feet today as the low-pressure system passes near the island, located about 200 miles north shortly after 3 a.m. today. Surf up to 25 to 35 feet this morning, lowering to 20 to 25 feet this afternoon is expected along the north and west shores of Kauai County, Oahu’s North Shore and the north shores of Maui and Molokai. The west shores of Oahu and Molokai can expect surf up to 12 to 20 feet this afternoon.

A high surf warning is in effect for the Big Island through 6 p.m. today.

“Large breaking surf, significant shorebreak, and dangerous currents make entering the water very hazardous,” the NWS said in a bulletin.

Snow showers and freezing fog are expected atop Haleakala this morning as a band of enhanced moisture over Maui heads east away from the island, weather officials say.

A winter weather advisory is in effect for the Haleakala summit through noon today.

“Plan on slippery road conditions along with blowing and drifting snow,” the advisory said. “Additional snow accumulation of less than 1 inch is expected.”

Two ground hornbill birds escaped from the Honolulu Zoo after a branch or tree fell on their enclosure today.

One was last seen heading toward the Ala Moana area and the other toward Kapiolani Boulevard.

Only one ground hornbill was thought to have escaped, but Mayor Kirk Caldwell told the Honolulu Star-Advertiser that its companion also is on the loose.

He described the initial escaped bird as “kind of a large bird, black, not very pretty looking in my mind.”

It has red skin on its throat and head and is “bigger than a chicken. It walks on the ground.”

Anyone who sees either bird should call 911.

Along with the zoo, the Wahiawa and Foster botanical gardens are closed because of the risk of falling trees and branches.

All city camping sites also will remain closed through Monday.

As many as 25,000 Hawaiian Electric Co. customers are without power and there could be isolated outages leaving as many as 30,000 “folks that are being inconvenienced,” Caldwell said.

“We’ve had reports of trees down, power outages, traffic signals malfunctioning,” Caldwell said.

He asked residents to postpone putting their trash or recycling bins out until as late as possible Monday morning, so they don’t blow away tonight.

1:25 p.m.

Three people — a motorist in Kunia and two pedestrians in Waikiki — suffered minor injuries today when they were hit by wind-whipped branches, trees or utility poles.

This afternoon, two Waikiki pedestrians were injured by separate wind-blown branches or trees — one on Kalia Road and one on Paoakalani Avenue.

Mayor Kirk Caldwell today reminded people to stay home, if possible, and definitely away from shorelines.

PREVIOUS COVERAGE

The National Weather Service in Honolulu has extended a high wind warning for Oahu until 6 a.m. Monday.

As of approximately 3:30 a.m. today, winds were blowing from the west at 25 to 40 miles per hour, with gusts of up to 60 mph. They are expected to shift to the northwest and peak later this afternoon into the evening, with strongest gusts over and downslope from higher terrain as well as through valley areas.

The NWS warns that winds this strong can make driving hazardous, cause damage to homes and result in dangerous flying debris. A higher number of downed trees and increased possibility of widespread power outages are also possible.

As of 5 a.m. today, a high surf advisory remains in effect for Kauai, Oahu, Molokai, Maui and Hawaii island; waves of 40 to 60 feet are expected along the north and west shores of Kauai and north shore of Oahu along with Molokai and Maui. West Oahu may see waves of up to 30 to 40 feet in height, while waves 8 to 12 feet high are expected on the west side of Hawaii island.

A high surf advisory is also in effect for the north shore of Hawaii island, with surf rising from to 10 to 16-foot level to 14 to 20 feet by tonight. Lanai, Kahoolawe and west Maui can expect waves from 8 to 12 feet in height.

High surf can result in damage to property along coastlines and ocean water affecting roadways, plus significant beach erosion and extreme harbor surges. Authorities urge visitors and residents to stay off beaches until conditions improve.

The city is discouraging outdoor activities such as surfing and hiking and warn that winds could cause trees and branches to fall without warning. Visitors are especially warned not to climb on rocky ledges near the ocean because of the danger of getting swept out to sea.

Mayor Kirk Caldwell is urging residents and tourists to remain vigilant as the storm is expected to move closer to the islands.

“Waves will be unruly and disorganized,” the city said in a statement.

The American Red Cross this morning planned to open a shelter at Waialua District Park at 67-180 Goodale Ave. in Waialua for residents evacuated from their homes due to potential costal flooding.

The Red Cross also opened a shelter Saturday night on Kauai at the Kilauea Neighborhood Center at 4260 Kene St.

Brigham Young University Hawaii has opened a shelter at its campus in Laie that would be available to public, according to the Red Cross.

The National Park Service warned of the possibility of hurricane force winds for the Summit District of Haleakala National Park. The park service warned that closures may occur without notice through midnight tonight because of visitor and employee safety.
