Reports are coming in that Agung is currently erupting. It does not sound like a huge event at this point… Stay tuned.
Tulamben, Mount Agung, Current Situation...

Typical. We leave from Singapore to Bali on 22 November, early morning with a 23 November flight to Sorong via Makassar. It’s probably too late to re-route thru Jakarta to Sorong.

It’s still ok mate, the smoke you see coming out is actually steam, there has been a bit of rain around and the water is running down through the cracks and venting as steam.
Still safe to visit at this stage

The alert level 3 has not changed with the steam-related eruptions.
Here you go, was quite dramatic looking, I have copied and pasted this from a local Bali FB group.
22 November daily volcano update.
Something to report! Yesterday about 5 p.m. Agung experienced a phreatic eruption, According to USGS, "Phreatic eruptions are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits. The intense heat of such material may cause water to boil and flash to steam, thereby generating an explosion of steam, water, ash, blocks, and bombs." A note late last night from the team at the observation post, stated (Google + my edits), "The enlarged fracture was observed from the satellite about 15 November. The Aster TIR satellite also captured the thermal energy increase on November 15, 2015. This morning (Tuesday) at about 8 am we flew the drones and the gas measurements on the plume this morning showed high levels of CO2 (carbon dioxide) and H2O (water). SO2 (sulfur dioxide) is low, possibly due to scrubbing factor, SO2 is trapped in hydrothermal water in the body of Mount Agung. But the high CO2 indicates that the observed white smoke has had a contribution of magma, this smoke is 100% volcanic origin. We've had discussions with the world's geochemists, they agreed that the smoke for this although dominated by water vapor but has a magmatic component that is substantial."
I'm attaching a wonderful time lapse video captured by Ineke Willebordse (C) published by Ubud Now & Then.

I'm also posting an infra-red photo of the ash column taken last night about 11 pm (that's how you see them at night). The ash was moving east-southeast, and a number of villages higher up on the mountain reported ash rain or falling ash last night.
The seismic numbers remain small, but overnight they include a mix of "blowing" quakes from the gas, harmonic and non-harmonic tremors.
We wait.

Not my words, but makes a lot of sense to me. YMMV.
"Yesterday just after 5 p.m. Gunung Agung experienced another phreatic eruption. That is an eruption where water meets hot magma and flashes into steam in an explosion, and the destroyed material around it becomes ash. Yesterday's explosion produced an ash column about 1500 meters high, and it was moving in a generally southerly direction.
"After this phreatic eruption, we started seeing more seismic activity, including non-harmonic tremors. There was one harmonic tremor early this morning (often linked with an eruption). The livestream monitoring camera from Bukit Asah (see link below) showed flaring lights till well after midnight, coming from the top of the mountain and numerous points on the high slopes. The light is NOT believed to be flowing magma, but light from inside the mountain reflecting off the ash and steam above it (like headlights in fog). The second livestream camera is at the observation post at Rendang (see link below) and has the clearest pictures this morning, although both of these change quickly with ash and weather conditions."

Garuda Airlines popup:
Virgin Australia just canceled the rest of their flights in and out today. The Aussie airlines tend to be the first to cancel flights. Airport remains open and other flights are operating normally

Not my words:
"Center for Vulcanology and Geological Disaster Mitigation states, the eruption that occurred in Gunung Agung is no longer phreatic, but it is a magmatic type eruption. That is, the material contained in the stomach of Mount Agung was out.
Despite the magmatic eruption, PVMBG stated that the eruption is still in the category of effusive eruption and has not erupted explosively, as happened in Mount Kelud.
"It is not yet explosive, it's still effusive," said Head of PVMBG Volcano Mitigation Division, I Gede Suantika at the Observation Post of Gunung Api Agung in Rendang Village, Rendang District, Karangasem Regency, Bali, Sunday, November 26, 2017.
This effusive eruption is characterized by the release of lava to the surface of the earth, sometimes accompanied by a small explosive eruption.
Therefore, according to Gede Suantika, PVMBG has not increased the status of volcanic activity of Gunung Agung to the highest level, namely alert and still maintain the status of volcanic activity of Mount Agung at level III, or standby status.
Gede Suantika said, at this time, the incandescent lava has come out and is moving to meet the floor of the crater of Mount Agung. Predicted, soon lava incandescent will slide from the top of the mountain.
"Lava still fills the floor, and when it's full, it will melt down," said Suantika.
To note, effusive eruption is characterized by lava discharging to the surface of the earth. Effusive eruptions have several features, among others, explosions do not occur, or the explosion only occurs occasionally. The magma is liquid.
Meanwhile, the peak of Mount Agung at this time can not be visually observed, because thick fog enveloped the mountain with a height of 3,142 meters above sea level. Even so, bursts of ash from the crater of the mountain can still be seen, because it has a gray-black color."
