Volcanoes National Park in Hawaii reopened on Thursday after shutting down on Wednesday due to harmful fumes. The trade winds, which blow from the east to northeast, returned to the area early Thursday. Sulfur dioxide was belching from Kilauea Volcano on Wednesday and was blowing in the direction of the Park. It was so bad on Wednesday that 2,000 people had to be evacuated from the area. Residents living in communities outside the Park were advised to remain alert to the possibility of worsening conditions in their areas.
