Moke

For the second week in a row, Hawaii Island, also known as the Big Island, faces threats from an intensifying storm.

Tropical Storm Moke is grinding towards Hawaii, bringing gusts of wind and heavy rain only a week after the islands faced similar conditions from Hurricane Lala.

On Saturday, Hawaii residents prepared for the latest storm, which is expected to pass south of Hawaii Island, the largest island in the Hawaiian archipelago, overnight and into the following morning.

As of 11am Hawaii Standard Time (21:00 GMT), Moke was located about 684 kilometres, or 425 miles, south of Hilo, a city on the eastern coast of Hawaii Island. It was moving west-northwest at 19km/h (12mph).

The National Hurricane Center (NHC) in the United States reported that the storm’s maximum sustained winds were about 85km/h (50mph).

Moke, like Lala, is forecast to spare the Big Island a potentially disastrous direct hit. But the island is still recovering from Lala, a Category 1 storm that spurred heavy flooding and power outages.

At least one person died in last weekend’s storm.

Lala came close enough to Hawaii Island to dump more than 1,000mm (39 inches) of rain in some locations, causing rivers to burst their banks.

High winds also bent tall palm trees and downed electrical lines, forcing nearly 130,000 utility customers to lose power.

Hawaii Governor Josh Green and other state officials have urged people to prepare for Moke by restocking food, medicine and other daily essentials ahead of the storm’s passage.

“It could certainly have a big impact because we’ve already been hit hard,” Green said in a video statement. “We’re pre-positioning all kinds of additional equipment and people. I’ve also authorised 100 rooms, hotel rooms, for people to go to, in case they don’t have enough services or protection, safety.”

Green added that, while power had been restored to most of Hawaii Island after Lala, some remote areas were still experiencing outages. Power is expected to be fully restored by September 8.

After passing Hawaii Island during the night, Moke is projected to continue on a westward path near the islands through early Tuesday, according to Casey Oswant, a meteorologist with the Honolulu office of the US National Weather Service.

“There will still be impacts, especially to the windward and southeast sides of the Big Island, but it will probably be a little bit more limited than what we saw with Lala,” Oswant said.

The National Hurricane Center projects that Moke will bring roughly 130mm to 250mm (5 to 10 inches) of rainfall over the next two days on the southeast and windward sides of the Big Island. Some isolated areas could see as much as 380mm (15 inches).

Eastern Maui, meanwhile, is likely to receive 76mm to 150mm (3 to 6 inches), with smaller amounts of precipitation expected across the rest of the island chain.

Governor Green warned that the heavy rain is unlikely to end with Moke.

“Everyone be very careful,” he said. “This storm will be followed by another storm front about a week later, and we continue to see the impacts of these major weather fronts that have hit Hawaii.”
