What is the polar vortex?
The polar vortex is a circulation of winds high up in the stratosphere, up to 30 miles above the earth.
It is present in winter and is not a new phenomenon, scientists have known about it for many years.
The winds regularly exceed 155 miles per hour – the strength of the winds in the strongest hurricanes.
During the winter it can strengthen and weaken. These changes have an influence lower down in the atmosphere and ultimately on our weather.
Are there any flood warning in place?
Natural Resources Wales has not issued any flood warnings or flood alerts. Four warnings have been removed in the last 24 hours.
