Flooding concerns in Hawaii after Cat 1 Hurricane soaked the region with nearly 2 feet of rain

Rain-Totals-Hurricane-Hone

Important Takeaways:

  • Hone continues to weaken and is a strong tropical storm Monday after it blasted Hawaii’s Big Island as a Category 1 hurricane with flooding rain, damaging winds and dangerous waves over the weekend.
  • The Central Pacific Hurricane Center (CPHC) in Honolulu said the storm made its closest approach to the Hawaiian Islands on Sunday morning, passing about 45 miles south-southwest of South Point, Hawaii. Peak winds were estimated to be about 85 mph.
  • The heavy precipitation associated with Hone had a major impact on Hawaii’s Big Island. Many areas picked up well over a foot of rain, sending water rushing down the steep slopes of the mountainous terrain and into low-lying neighborhoods. Because the ground was extremely saturated, there were also concerns about mudslides and landslides.
  • More than 21 inches of rain fell across Hakalau, with Saddle Quarry receiving nearly 20 inches. Keauomo, Nene Cabin and Waiakea Uka each received more than 16 inches of rain.
  • Flash Flood Warnings were issued through Sunday as heavy rain lashed the area, and forecasters estimated rainfall rates of 2 inches an hour.
  • As of early Monday morning, poweroutage.us showed more than 16,500 outage reports on the Big Island.

Lava threatens Hawaii exit routes, could spur more evacuations

PAHOA, Hawaii (Reuters) – Lava flowing from giant rips in the earth on the flank of Hawaii’s erupting Kilauea volcano threatened highways on Monday, raising the possibility officials may order thousands more people to evacuate before escape routes are cut off.

Lava from a huge new fissure tore through farmland towards a coastal dirt road that is one of the last exit routes for some 2,000 residents in the southeast area of Hawaii’s Big Island.

More lava-belching cracks are expected to open among homes and countryside some 25 miles (40 km) east of Kilauea’s smoking summit, possibly blocking one of the last exit routes, Highway 132.

Fountains of magma spouted “lava bombs” more than 100 feet (30 meters) into the air as the molten rock traveled east-southeast towards the coastal road – Highway 137 – the Hawaiian Volcano Observatory said.

Mass evacuations would be triggered if either highway is hit by lava, said Hawaii National Guard spokesman Jeff Hickman.

“There’s a lot of worst-case scenarios and roads getting blocked is one of them,” said Hickman, standing on Highway 137, in the potential path of the lava flow, some two miles (3 km) away.

ERUPTIONS COULD LAST WEEKS

Dozens of homes have been destroyed since eruptions began 10 days ago and officials have ordered the evacuations of nearly 2,000 residents in the lower Puna district of the Big Island, home to around 187,000 people.

The American Red Cross said 500 people sought refuge in its shelters on Sunday night because of worsening volcanic activity.

Two more fissures opened in the past 24 hours, bringing the total to 19.

“It’s optimistic to think that this is the last fissure we’re going to see,” said Hawaiian Volcano Observatory Deputy Scientist-In-Charge Steve Brantley. A similar seismic event in 1955 lasted 88 days, he said.

Unnerved by near-constant small earthquakes and emissions of toxic sulfur dioxide gas, Rob Guzman and his husband Bob Kirk left their home in Kalapana Seaview Estates while they still could.

“We just need the local government to calm down the panic that some of these 2,000 people are feeling, that today, we’re going to be trapped with no way out,” said Guzman, who left behind a banana farm and rental properties to go stay with friends.

The Hawaii Fire Department issued a “condition red” alert on Monday because fissures in the southeast area of the Lanipuna Gardens area were issuing high levels of sulfur dioxide.

“Condition RED means immediate danger to health so take action to limit further exposure. Severe conditions may exist such as choking and inability to breathe,” the department said in the alert.

While residents deal with noxious gas and lava on the ground, the U.S. Geological Survey is concerned that pent-up steam could cause a violent explosive eruption at the volcano crater, launching a 20,000-foot (6,100-meter) plume that could spread debris over 12 miles (19 km).

Scientists had expected such explosions by the middle of this month as Kilauea’s lava lake fell below the water table. The possibility exists, however, that water may not be entering the crater, as feared, and gas and steam may be safely venting, scientists said.

“So far those explosions have not occurred and I think the key here is that the vent system is an open one, therefore pressure is not being built or developed down at the top of the lava column,” Brantley told a conference call.
