230mph jet stream to bring storms to Northern Ireland
A 230mph jet stream is set to bring fresh storms to Northern Ireland on Friday.
It's batten down the hatches time again as the UK is set to feel the force of strong winds over the coming weekend.
The Met Office tweeted a map showing how the region will be at the centre of the jet stream's fastest winds.
It warned: 'Powerful 230mph #jetstream to bring stormy weather for northern areas Fri and Sat #WeatherAware'.
Northern Scotland is predicted to be worst affected by the gales.
A jet stream is made up of 'ribbons of very strong winds which move weather systems around the globe'.
They are found 9-16km about the surface of the earth.
It can either improve or delay flight times depending on the direction which the plane is travelling, for instance flights home from the USA often take less time than flying out.
