UK storms – data and impact on drivers

Driving in the UK comes with several challenges – and adapting to changing weather conditions is one of them.

In this know how guide, we look at storms in the UK, when the next one will land, and what drivers should do.

How many days does it rain in the UK?

According to Statista, the UK typically has between 15 and 22 days of rain every month. This averages out to around 156 days a year.

Scotland receives more rain than England, Wales, and Northern Ireland.

England is the driest of the four nations.

The Atlantic Ocean drives precipitation into northern and western areas, explaining why Scotland is wetter than England.

How many storms are there every year in the UK?

The Statista data shows that there is an average of 10-20 storms every year in the UK – with two to five receiving names from the Met Office.

Since naming began in 2015, the number of named storms has had a low of two in 2022/23 season – and a high of 12 in the 2023/24 season.

Scotland, Wales, and western England are normally the worst affected areas.

Storm names for 2025/2026 season

These are the names of the storms that have hit the UK so far in 2025 and are set to impact the UK before the end of the 2026 season.

1. Storm Eowyn – Hit the UK on the 24th January 2025
2. Storm Floris – Last two days, from the 4th to the 5th August 2025
3. Storm Amy – Impacted the UK from the 3rd to 4th October 2025
4. Storm Benjamin – Moved up from central Europe and affected parts of the UK on the 23rd October
5. Storm Claudia – Starting from today and lasting until Sunday 16th November
6. Storm Bram - Starts today and ends on Wednesday 10th December
7. Storm Goretti - First of 2026, and it lasted two days from Thursday 8th January until Friday 9th January
8. Storm Chandra - Strong winds will take place on Monday 26th and Tuesday 27th January

These are many names that are prepared for the next storms to arrive in the UK over the next few months.

The Met Office will release these names when there is forecast to be a storm.

New names for storms are released every September and run to the following August.

Why do storms get a name?

In the UK, storms are named when they pose a risk of disruption or damage likely to trigger amber or red warnings.

This decision comes from the National Severe Weather Warnings service, which weighs both the potential impact and its likelihood.

While strong winds and heavy rain are the usual triggers, other severe weather types may also lead to a storm being named.

When a storm meets the criteria for naming, meaning it poses a risk of significant disruption or danger, the responsibility for assigning its name falls to one of three national meteorological services: the UK’s Met Office, Ireland’s Met Éireann, or the Dutch KNMI.

Together, they form the western Europe storm naming group.

The chosen name is taken from the annually approved list, which is arranged alphabetically and alternates between male and female names.

This system ensures consistency, helps the public easily identify severe weather events, and raises awareness of potential impacts across the region.

What is classed as a storm?

A storm is a violent atmospheric disturbance marked by strong winds, heavy rain, thunder, lightning, and/or snowfall.

It occurs when areas of low pressure intensify, creating unstable weather conditions over both small and larger areas.

Storms often leading to flooding, property damage, and risks to human safety when driving.

What is a ‘weather bomb’?

A weather bomb is a low-pressure system that drops 24 millibars in 24 hours, a process called explosive cyclogenesis.

Driven by the jet stream, falling pressure pulls in surrounding air, tightening rotation like a spinning skater.

The resulting winds can peak quickly, strong enough to topple trees, damage buildings, and cause havoc on the roads.

What is a ‘storm surge’?

A storm surge is a rise in sea level driven by a storm, often causing severe coastal flooding.

Fierce winds push seawater toward the shore, piling it up, while low pressure at the storm’s centre adds a smaller lift – about 1 cm for every millibar drop – known as the inverse barometer effect.

Powerful winds also generate large waves that can batter sea defences or spill over, heightening flood risks. In tropical storms like hurricanes, heavy rainfall further compounds the danger.

When is the next storm?

The Met Office has introduced Storm Chandra as the next named system, expected to sweep across the UK on Monday night and into Tuesday with powerful winds, heavy rainfall, and areas of snow.

Forecasters warn that some locations could face flooding and travel delays, while higher ground in northern England and parts of Scotland may see notable snowfall.

A series of weather alerts has already been issued, including amber warnings for heavy rain in south‑west England and strong winds along Northern Ireland’s eastern coastline.

Wider yellow warnings cover the whole of Northern Ireland, a broader stretch of south‑west England, and selected areas of northern England and Scotland.

How can drivers prepare?

The RAC is warning of “more misery for motorists” as Storm Chandra is named as the next major storm this week. Following weeks of heavy rainfall, flooding is likely and drivers shouldn’t take risks driving with ongoing vehicle faults. 

RAC mobile servicing and repairs team leader Nick Mullender said: “Another named storm is set to heap more misery on motorists, with drivers in the south‑west of England once again bearing the brunt after weeks of relentless rain.

"Flooding is highly likely, making many roads dangerous. Our message to drivers is simple: do not drive through standing water unless you are completely certain the water is shallow enough and it's safe to do so.

“In these conditions, drivers need to slow down and stay alert. Wet roads can double stopping distances, so taking a cautious, steady approach and allowing extra time to react is essential.

“And if your vehicle already has known faults, now is not the time to take risks. Avoid unnecessary journeys and get issues fixed promptly by a trusted mobile mechanic or local garage.”
