An area of low pressure is set to sweep in off the Atlantic Ocean caused by an unusually strong jet stream for the time of year.

Weather forecaster Liam Dutton reports that the jet stream is travelling at around 140mph at about 30,000ft.

The jet stream is said to be also acting as an atmospheric superhighway, bringing the low pressure towards the UK.
