Indonesian authorities said the airport in the resort island of Bali will reopen on Wednesday after a volcanic eruption had shut the facility for the past two days.

The volcanology agency lowered the aviation alert to orange from the highest red, Arie Ahsanurrohim, spokesman for Bali airport, said in a text message. The Ngurah Rai International Airport will resumed services from 3 p.m. local time. The facility, which authorities said earlier would remain shut until 7 a.m. Thursday, was closed after the Mount Agung volcano continued to belch smoke and ash and experts warned of an imminent large eruption.

PT Garuda Indonesia, the national flag carrier, will operate six flights on Wednesday out of Bali to cities including Jakarta, Labuan Bajo and Surabaya, it said in a statement. Singapore Airlines Ltd. said it will resume services from Bali and was seeking approval to operate additional flights for those affected by cancellations earlier this week.

Mount Agung in Bali has been rumbling since September, prompting authorities to set up exclusion zones extending as far as 10 kilometers (6.2 miles) from the crater. The government raised the alert status to the highest level on Monday, as ash soared as high as 7,600 meters from sea level. The spreading cloud is dangerous for aircraft as jet engines may not be able to handle the debris from the volcano.

Bali airspace was free of volcanic ash and was safe for operations, state airport operator PT Angkasa Pura I said in a statement. The airport handles about 2,600 international flights a week, according to CAPA Centre for Aviation.

Airlines such as Korean Air Lines Co. and Cathay Pacific Airways Ltd. have scrapped flights. Singapore Air previously made arrangements to move its passengers by buses and ferries to Surabaya for flights to Singapore, according to its website. Cathay said its flights on Nov. 29 and Cathay Dragon flights on Nov. 30 have been canceled.

Garuda said it has also resumed flights to Lombok International Airport on the neighboring island of Lombok. The national flag carrier also said it will deploy extra flights between Surabaya and Jakarta.

As of Monday afternoon, 445 flights and thousands of tourists were affected, according to Air Transport Director General Secretary Pramintohadi Sukarno.
