TORRENTIAL rainfall, strong winds and flooding is forecast to beset the UK by what could be named as Storm Deirdre within the next 48 hours.

A storm system yet to be named by meteorologists is forecast to sweep across Britain on Friday, hurling a cocktail of wet and windy weather at the nation.

A yellow weather  warning has been issued by the Met Office as the low pressure system bears down on the UK through the Atlantic Ocean.

A warning covering parts of Northern Ireland, northern England, Scotland and Wales, will come into effect at 3am on Friday and will remain in place until midnight.

The Met Office typically names a storm at least 24 hours before it hits if the criteria for severe weather impacts is deemed to have been met.

A storm will be named when it has the potential to cause an amber “be prepared” or red “take action” warning, according to the criteria used by the National Severe Weather Warnings service.

A spokesperson for The Weather Channel said: “Based on the current forecast, it is possible that this storm will be named by the UK Met Office and Irish Met Éireann as Storm Deirdre, with high winds and surface flooding possible.”

Storm Deirdre will follow Ali, Bronagh and Callum, all of which impacted the UK with severe weather at various points in September and October.

The Met Office’s yellow “be aware” weather warning was this morning extended to parts of northern Scotland. 

Delays or cancellations on public transport, longer journey times on the roads, power cuts, damage to buildings and large waves in coastal communities are expected when the warning comes into effect, the Met Office said.

Flying debris blown by strong winds reaching 80mph in places could cause injuries and pose a “danger to life” in some cases, according to Met Office advice.

The weather advisory reads: “A weather system will move eastwards across the north of the UK on Friday bringing widespread gales.

“Inland gusts of 60-70mph are possible across north Wales, northern England, northern Ireland and all of Scotland, with gusts of 80mph in exposed locations in northern Scotland.

“There remains some uncertainty in the track of this system and where the strongest winds will occur. Heavy rainfall may be an additional hazard across parts of northern and western Scotland.”

Wales faced heavy downpours on Wednesday after a severe weather warning was issued in parts of the country.

The Met Office said homes and businesses in the worst-hit areas could also potentially face flooding as Storm Etienne passes over the UK.

The storm was named by the IPMA Portuguese weather service after it was first detected in the Azores region of Portugal, and is currently making its way over western parts of the UK.

In Wales, areas including Pembrokeshire, Carmarthenshire, Ceredigion, Powys and Swansea, were the worst affected, with warnings of “heavy rain and possible flooding” in place until 12pm.

The Met Office said: “Bands of heavy rain are expected to cross Wales on Wednesday, with the south and south-west perhaps seeing the heaviest rain later in the morning.”

The service added that up to 2in of rain could fall in some hilly locations, and has issued a yellow warning for icy patches.

Natural Resources Wales had nine flood alerts and one flood warning in place across south and west Wales, with the most severe threat to the River Gwendraeth Fawr at Pontyates and Ponthenry near Llanelli, which the Welsh government said required “immediate action”.

The Met Office said the following three weeks until Christmas will see repeated Atlantic gale batterings and travel disruption.

With freezing conditions expected in the coming weeks, bookmaker Ladbrokes is offering odds of 10/11 that record-breaking low temperatures are recorded this winter.

Meanwhile, it’s the same price that any part of the UK sees snow on Christmas.

Ladbrokes spokesman Alex Apati said: “It’s looking more likely than ever that this winter breaks records, with a White Christmas being just as likely.”
