Met Eireann have explained a rare phenomenon spotted over Dublin skies this morning.
Wavy clouds appeared in the Malahide area with many questioning why they appeared in this unusual manner.
Weather chiefs took to social media to explain that the clouds spotted were Kelvin-Helmholtz clouds.
A forecaster tweeted this morning: "Kelvin-Helmholtz clouds spotted from Malahide this morning.
"A rare phenomenon, where a cloud produces a billowing wave pattern. They occur when there is a strong vertical shear between two air streams, causing winds to blow faster at the upper level than at the lower levels."
These wave like clouds are described as extremely rare and generally occur on windy days.
The Met Office UK has the following details about the rare clouds;
All you need to know about the rare phenomenon:
Height of base: Can be any height, but usually at higher levels.
Shape: A repeating breaking wave pattern.
Latin: These clouds are named after Hermann von Helmholtz and William Thomson, Lord Kelvin, physicists who studied turbulent airflow. There is no Latin etymology.
Precipitation: None.
The first few days of lockdown are going to be hellish as Met Eireann is forecasting heavy rain and very strong winds this week.
Met Eireann predict the grim weather is because of an "area of low pressure", which will sweep across Ireland this weekend.
