According to the local authority’s decision, Ngurah Rai airport has been closed from 3am to at least 7pm (Indonesia time) on June 29.
Based on the meteorology agency’s prediction, the volcanic ash will reach the airport on June 29’s morning, said spokesman of the airport Yanus Suprayogi, adding that the airport closure can be extended after 7pm if necessary.
