Vog is expected to stick around through the weekend, according to the National Weather Service.

Forecaster Pete Donaldson said southeast winds are blowing volcanic emissions from the Hawaii island toward Oahu and other islands. That pattern is expected to persist through Saturday and possibly longer, he said.

Vog causes irritation to the eyes, nose, throat and lungs, especially for those with respiratory conditions like asthma and emphysema.

The American Lung Association-Hawaii Chapter recommends individuals with breathing problems stay indoors and use an air conditioner set to recirculate indoor air as a way of preventing outdoor air from entering the home. Individuals sensitive to vog also should have their medications on hand, stay hydrated and avoid outdoor physical activity.

OHA named co-trustee of marine preserve

The Office of Hawaiian Affairs now has an official voice in the management of the world’s largest marine conservation area.

Gov. David Ige announced Thursday that OHA has been added as a co-trustee of the Papahanaumokuakea Marine National Monument.

President Barack Obama last year expanded the monument to encompass about 583,000 square miles of protected ocean.

OHA’s support of the expansion was contingent on having a say in the monument’s management, including advocating for Native Hawaiian access.

OHA Chief Executive Officer Kamana‘opono Crabbe says the historic action places Native Hawaiians at the highest levels of decision making for a culturally and spiritually significant place.

Other co-trustees are the National Oceanic and Atmospheric Administration, U.S. Fish and Wildlife Service and state Department of Land and Natural Resources.
