A yellow weather warning for rain has been issued by the Met Office, covering Monday 9th February from 12:00 until 23:59.

Heavy rain during the afternoon and evening may lead to flooding and disruption, particularly on roads and public transport.

What to Expect

The warning says spray and flooding on roads are likely, which could make journey times longer. Bus and train services are also likely to be affected, with delays possible.

There is a chance that a small number of homes and businesses could experience flooding. The Met Office also says there is a possibility of some interruption to power supplies and other services.

Rainfall Details

Bands of rain and heavy showers are expected to move east across southern parts of England and Wales during the afternoon and evening. Rainfall totals of 10 to 15mm are likely in many areas, with 20 to 30mm possible in places exposed to strong south to southeasterly winds.

Advice for the Public

People are advised to check whether their property could be at risk of flooding and, if so, consider preparing a flood plan and an emergency flood kit.

Those travelling are encouraged to check road conditions if driving, or bus and train timetables, and to amend travel plans if necessary.

The Met Office also advises preparing for potential power cuts by gathering items such as torches, batteries, a mobile phone power pack and other essential supplies. It adds that weather warnings can change quickly and recommends staying up to date with the local forecast.

Why the Warning Is Yellow

The warning is classified as yellow because it has a medium likelihood and a low impact.
