Eyewitness Hannah Murphy told CNN: "Walking towards the beach it looked to me like a huge wave coming from the back of the ocean about to swamp us all!"
"People were running from the streets to capture the unbelievable cloud formation."
The Belfast Telegraph reports that the Australian Bureau of Meteorology issued a severe thunderstorm warning for some areas in Sydney.
According to Wikipedia, an arcus cloud is a low, horizontal cloud formation. Roll clouds and shelf clouds are the two types of arcus clouds. A shelf cloud is usually associated with the leading edge of thunderstorm outflow; roll clouds are usually formed by outflows of cold air from sea breezes or cold fronts in the absence of thunderstorms.
