2. NOTAM or “Notice to Airmen”.
This site lists all the NOTAM for the Bali airport. This site is designed for pilots and airline staff and takes some practice to decode. This is where you can find when the airport closes and for how long. If the airport is open no NOTAM will be listed. Timings here are also UTC and if in Bali you need to add 8 hours.

3. Australian Bureau of Meteorology.
This site has graphics of the current ashcloud and forecasts within the next 6, 12 and 18 hours. The timings are UTC time. This means that if you are in Bali you need to add 8 hours to the timings on the forecasts.

2015 Bali ash cloud from Rinjani volcano

Mount Rinjani is an active volcano on Lombok Island (east of Bali). Rinjani is 3,726 metres tall making it the second highest volcano in Indonesia after Mount Kerinci (3,805m).

The volcano eruption is actually on Mount Barujari which is a “child” volcano of Mount Rinjani. Barujari is a post-caldera cone that is in the Rinjani lake.

Mount Barujari started erupting on Sunday, 25 October 2015, at 10:04am. Below are a series of satellite pictures taken almost daily. On some pictures you can clearly see the ash cloud blowing from east to west direction Bali.

Have a look here at the July 2015 ash cloud satellite images caused by the Raung Volcano.

Bali airport flight disruptions

The volcano ash cloud has been drifting towards Bali causing the Bali airport to close for some time. The longest the Bali airport was closed so far was for 43 hours. This was from 3 November (19:30h) to 5 November (14:30h).

Nearly 700 flights where cancelled during these 43 hours and thousands of passengers were left stranded either in Bali or on the way to Bali.
