Public transport services are likely to face delays and cancellations, and residents are advised to prepare for possible power cuts during the storm.

The warnings indicate that flooding may disrupt train and bus services, and some communities could be cut off due to flooded roads.

The Environment Agency has warned against driving through floodwater, emphasizing that just 30cm of flowing water can float a car, and urges residents to sign up for flood warnings.

Localized flooding is also anticipated in the south-west of England and Cumbria during this period.

Looking ahead, the forecast includes a mix of sunny spells and showers, with more rain expected on February 26.

Major cities affected by the warning include Cardiff, Newport, and Swansea, where persistent and heavy rainfall is anticipated throughout the afternoon and evening.

The Met Office has issued an amber rain warning for parts of south and mid-Wales, effective from the afternoon of February 23 until early morning on February 24, due to expected torrential rain.

In addition to the amber warning, yellow warnings for wind and rain have been issued across much of the UK, including Wales, Northern Ireland, Scotland, northern England, south-west England, and the West Midlands.

A separate weather warning is in effect for nearly all of Wales, covering additional areas of concern for flooding during the same timeframe.

Forecasters predict that up to 100mm of rain could lead to fast-flowing and deep floodwater, creating a significant danger to life.

Winds are expected to reach up to 60mph, with gusts potentially hitting 70mph in some areas.

The severe weather may lead to surface water and river flooding, with strong winds contributing to poor driving conditions and potential road closures.
