Another yellow weather warning has been issued for parts of Powys as the area gets set for heavy rain and flooding associated with Storm Jocelyn.

The Met Office officially named Storm Jocelyn on Monday (January 22) as strong winds and heavy rain are forecast to hit the UK on Tuesday and Wednesday (January 23 and 24).

The announcement came as Powys and the UK endured the back end of Storm Isha which battered the country on Sunday and Monday (January 21 and 22) with winds of up to 107mph.

These strong winds resulted in flight, train and ferry cancellations as well as road closures and power cuts.

The Met Office announced yellow weather warnings for Powys on Monday due to strong winds associated with Storm Jocelyn. 

These wind warnings will be in place on Tuesday and Wednesday.

The Met Office has now revealed another yellow weather warning will be in force on Tuesday (January 23) due to heavy rain and flooding associated with Storm Jocelyn. 

The yellow weather warning will be in place on Tuesday between 12.30pm and 7pm and will affect parts of Powys including Newtown, Machynlleth and Brecon.

How to prepare for the yellow weather warning and Storm Jocelyn

The Met Office has issued advice on how to prepare for the yellow weather warning in place on Tuesday and the threat Storm Jocelyn poses.

A Met Office spokesperson said: "Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

"Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

"People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items.

"Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area."

The yellow weather warning will be in place across Powys from 12.30pm to 7pm on Tuesday, January 23.
