LIHUE — The vog, which is caused by sulfur emissions from the Kilauea Volcano on the Big Island, made its way to Kauai Sunday night, said Derek Wroe, a forecaster with the National Weather Service on Honolulu.
“We’ve had a long stretch of light and variable winds that have been blowing from the Big Island,” Wroe said. “The southerly winds are drawing the vog to the top of Kauai,” he said.
The vog won’t linger long, Wroe added.
“We have a front with northerly winds coming in, that will sweep the vog out,” he said.
The vog is expected to leave this morning.
But because the vog is caused by volcanic emissions, it can be hard to measure and track, Wroe said.
“We don’t know how many emissions the volcano releases at a given time,” he said.
This isn’t the first time this year Kauai has felt the effects of the Kilauea Volcano. In January, southeast winds coming from the Big Island swept vog across the ocean to Kauai.
While people with pre-existing respiratory conditions are more likely to have health issues from an increase of vog in the air, symptoms include headaches, watery eyes, sore throat and breathing difficulties, according to a release from the Hawaii State Department of Health.
