The Met Office has said a tornado could hit western parts of the UK amid Storm Isha.
A "tornado watch" zone was issued for Northern Ireland, as well as parts of Scotland and northern England by the Tornado and Storm Research Organisation (Torro) earlier today.
The warning means a “strong tornado” is possible in those regions.
Met Office forecaster Marco Petagna said: "There is a potential that we could see the odd isolated tornado largely tied in with the squally cold front mainly in western parts of the UK on Sunday evening.

“They can cause some significant damage but often on a very localised scale, they often don’t tend to last very long."
Meanwhile, Network Rail said 50mph speed restrictions will be imposed across most routes as a precautionary safety measure.
Amber warnings for wind have been issued for the majority of the UK.
These warnings are expected to remain in place until 6am tomorrow, Monday.
