Watch mesmerizing 'Levanter cloud' as it billows over the Rock of Gibraltar

The Levanter cloud formed Wednesday and is said to be a common sight when warm, moist easterly winds from the Mediterranean are forced upwards over the Rock of Gibraltar.

Travelers at the Gibraltar International Airport were treated to a mesmerizing site as a Levanter cloud formed over the Rock of Gibraltar.

The stunning scene happened Wednesday and is said to be a common sight when warm, moist easterly winds from the Mediterranean are forced upwards over the Rock of Gibraltar. The air then cools as it rises, and the air condenses into a cloud. 

"This cap cloud can be sculpted by the shape of The Rock if conditions are just right," the FOX Forecast Center said.

The Levanter cloud is a type of banner cloud, where air flows around a mountain. 

The Met Office in Gibraltar took the time-lapse video and shows how persistent the mile-long cloud can be.

The office and the Port Authority kept a ‘Strong Wind Warning’ in place for a good part of the week, with the wind blowing at 16 mph and gusting to 35-40 mph, helping to form the cloud.
