Bribie Islanders and parts of the SE Queensland coast were in for a treat for all weather lovers and those with a keen eye when an extremely rare roll cloud barrelled its way over us a few days ago.

These rare cloud formations come in a few variations and can be caused by various weather conditions, such as wind changes, where cool air meets warm air and interact causing an uplift of cloud along the leading edge of the wind change. They can also cause air turbulence for planes.
A rare type of this cloud is called “The Morning Glory” and can be seen around the world, at particular times of the year. In parts of Northern Australia and east coastal parts, it can be seen at regular intervals.
These cloud formations often look like they are travelling at high speed, have a rolling motion and can stretch from horizon to horizon. They have reported speeds of over 60 km an hour and sometimes are accompanied by a strong wind gust as the wind change moves up the coast or across the area.

This was one captured in the United States.
