A bizarre cloud formation surprised commuters as they made their way to work last week on the Portuguese island of Madeira.
Weather blogger Rogerio Pacheco witnessed the cloud and decided he had to act quickly, reported the Daily Mail: "As soon as I saw the sky, I was immediately intrigued and I just had to grab my camera to take a photo."

Emma Sharples, a meteorlogist from the UK's Met Office, told the BBC the cloud formaction actually was not unusual.
But Pacheco's timing was exceptional, capturing a lower cloud as it caught the sun's scattered light, just as it was making contact with a higher cloud.
"I think the presence of a rising sun has made (it) appear more striking than the clouds alone would appear," Sharples said.
"We think they are probably cumulus clouds (cauliflower-shaped and fluffy), so pretty common, but enhanced by the light conditions."
