A tendril of ash from the Southern Ocean has moved rapidly to south-east Australia, driven by an intense low and strong southerly winds. The ash is forecast to clear throughout today and into tomorrow (Wednesday) - with the bulk forecast to clear tomorrow evening.

Director of the Bureau of Meteorology's Volcanic Ash Advisory Centre in Darwin, Dr Andrew Tupper, said the ash cloud has travelled over 4000 km in the past 24 hours at a speed of 170-190 km/h.

"The ash is still clearly visible on satellite imagery, and has been observed by a number of pilots flying at lower altitudes.

"The volcanic ash cloud is now more than two weeks old, and generally between 8 and 13 km (26 000 to 42 000 ft) in altitude, with the leading edge at an altitude of approximately 10 km (32 000 ft)," said Dr Tupper.>> More
