Hana High and Elementary School will be closed today due to continuing trouble with the local water supply, the Department of Education announced.

Also affected, according to the county, are Hana Medical Center, Waianapanapa and Uakea Road residents.

Starting today, and possibly as long as six months, those customers will receive water from a second well that was due to come on line in February, said county spokesman Rod Antone. The Health Department is testing the water quality as a precaution.

The water supply in the area has been affected by problems with the electrical well pump for about a week, and the county has urged residents to conserve water until the problems are fixed.

A Department of Education spokeswoman said by email the department will decide today whether the Hana school will reopen Tuesday.

Customers can call the Water Quality Laboratory at 270-7550 for updates. They can also contact the department’s 24-hour service line at 270-7633.

Rain reaches 2 inches an hour

Hawaii island was under a flood advisory for most of Sunday as heavy showers and thunderstorms pelted Hilo, Puna, Kau and Hamakua.

At some points during the afternoon, rainfall reached 2 inches per hour, the National Weather Service said. But Hawaii County Civil Defense reported no significant flooding.

Affected communities included Hilo, Hawaiian Paradise Park, Honokaa, Honomu, Keaau, Kukuihaele, Pohakuloa Training Area, Naalehu, Waimanu Valley, Waipio Valley, Pohakuloa Camp and Pahoa.

On the summits 3 to 6 inches of snow was expected overnight.

Quake shakes Big Isle

A magnitude-4.5 earthquake rattled Hawaii island Sunday but caused no damage or tsunami.

The quake struck at 6:30 a.m. in the ocean about 28 miles south-southeast of South Point, according to the U.S. Geological Survey. The epicenter was at a depth of 23 miles, the agency said.

Such quakes off the Big Island usually result from the release of stress from the weight of the island on the seafloor.
