The eerie weather phenomenon was photographed and filmed over the city on Tuesday afternoon, with many querying what the reason was for the strange formations.
"Is it aliens?" one man asked. "I feel that as a society we all have the right to really know what is going on. Should we be concerned?"

"What is going on?" said another. "Help."
But experts say there is an easy explanation for the unique cloud formations.
"These clouds are known as gravity waves," Sydney's 7NEWS weather reporter Angie Asimus said.
"In a westerly wind pattern, the air rises and cools as it goes over the mountains and then cools and condenses on the way down.
"The rise and fall creates these long clouds."
Although interesting to look at from the ground, Asimus warns the clouds could be trouble for air travellers.
"These (clouds) can also be a sign of turbulence for aircraft."
Comment: Chemtrails, and geoengineering, are indeed real, however, whilst these rather nefarious practices have gained significant traction in the public consciousness in just the last year or so, they seem to be distracting from another the significant changes occurring in our atmosphere - which is also evident in a variety of other strange sky phenomena, including Transient Luminous Events, iridescent clouds, low lattitude and multicoloured aurora, to name a few - and which, unlike those man-made problems, cannot be stopped, and foreshadow greater Earth Changes up ahead:

The turbulence comment is notable because in recent weeks there have been a few notable 'extreme' turbulence incidents: Another severe turbulence incident strikes passenger plane, follows death of passenger in similar incident 1 week earlierAlso check out SOTT radio's:
