ORIGINAL COVERAGE:
The mood this morning at Hawaii County Civil Defense headquarters in Hilo was cautiously optimistic as Tropical Storm Olivia continues to track to the north of the Big Island.
If the current forecast track holds, the tropical cyclone will have a bigger effect on Maui than Hawaii Island. Mayor Harry Kim said, however, those tasked with emergency management for the Big Island will continue to track the storm.
“We monitor it because we know storms are as unpredictable as unpredictable can be,” Kim said. “The mission today … is to continue to track it, continued planned review. … At this point, I do not believe, unless something is dramatically changed, that wind will be a factor or hazard. I do not believe, unless something changes, that surf will be a real hazard, but we’ll monitor. But at this point, we look pretty good.”
As of 8 a.m. the center of Olivia was 240 miles east-northeast of Hilo with maximum sustained winds at 65 mph, moving west at 10 mph. Tropical-storm-force winds extend outward up to 90 miles from the storm’s center. Gradual weakening is forecast during the next 48 hours, but Olivia is expected to remain a tropical storm as it moves over the islands.
Deanna Marks, a National Weather Service meteorologist, told those at the briefing Olivia “continues to weaken and become more disorganized as she pushes westward.”
“It looks like it going to take that southwesterly turn later today and … impact Maui more so than the Big Island,” Marks said. “… It looks like the northern portion of the island could see some stronger wind gusts.”
“Waimea and north would probably see some gustier winds, Kohala, Kohala Mountains area,” she added.
The Air Force Reserve Hurricane Hunters continue to fly today into the storm and send data back to the weather service, Marks said.
The outermost shower bands associated with Olivia are gradually spreading across the islands, and although a tropical storm warning remains in effect for Hawaii Island, forecasters are also backing off the amount of rain the island is expected to receive.
“What we’re looking at is more 2 to 4 inches with isolated 6 inches for the windward and southeast portions of the Big Island. Kona side, 1 to 3 inches,” Marks said. “Absolute worst-case scenario 4 to 6 inches with an isolated 8 inches. That’s for the duration of the storm. So that would be beginning later this evening through Thursday morning.”
“As far as surf goes, we’re backing off on that, as well,” she continued. “We do still have a high surf warning in effect, but as far as surf heights go, we’re taking that back a bit to maybe 10 to 15 feet, and that would be on the very high end. So we’re not expecting an extreme an impact as initially expected, and that’s with the track pushing further north towards Maui.”
The state Department of Education last night walked back a decision made yesterday to curtail all after-school programs and it will be business as usual today at Big Island public schools.
“All roads are open; all schools are open at this time. We’ll continue monitoring,” Civil Defense Administrator Talmadge Magno said.
The state Department of Land and Natural Resources closed all East Hawaii parks, forest reserve and wildlife areas today, but county parks remain open.
“The decision was made yesterday not to close any of our parks, or anything … because the forecast appeared to be accurate and the radius of the tropical storm winds would not be anywhere near Hawaii Island,” Kim said.
“… In the event that something changes in the forecast, we’ll be there to notify you ahead of time, so you won’t get caught up.”
