Tornado spotted in Powys following thunderstorm warning
A tornado was spotted in Powys following thunderstorms in some parts of the country.
Della Morgan posted the photo after discovering the tornado in Merthyr Cynog.
It came after warnings of heavy showers and thunderstorms across most of Wales on Tuesday.
Yellow weather warnings for thunderstorms are still in place for most parts of Wales.
The Met Office has issued a thunderstorm warning across large parts of the UK, saying heavy and slow-moving downpours could lead to flooding and disruption in some places.
What is a tornado?
Tornadoes form when the weather is 'unstable' and showery.
They are spinning columns of air that reach the ground from cumulonimbus (thunderstorm) clouds - which are low level clouds.
It forms as air starts to spin due to winds at different heights blowing at different speeds, creating wind shear.
It causes the air to start spinning horizontally. If it gets caught in a supercell updraft, the updraft tightens the spin, speeds it up and tilts it towards the ground.
As they develop we often see funnel shaped clouds extending from the base of the cloud. A tornado forms only when these funnel clouds touch the ground.
