Advice from the Met Office

People are being advised to check if their property is at risk of flooding and to prepare a flood plan and emergency flood kit.
The Met Office adds that people cope better with power cuts when they’ve prepared in advance, suggesting the gathering of torches, batteries, a mobile phone power pack, and other essential items.

They also remind the public that weather warnings can change quickly, recommending that everyone stay up to date with the latest forecast for their area.

Why Yellow?

The yellow warning has been issued because the weather has a medium likelihood and a low impact according to the Met Office.
