Looking at the latest air pollution data, external for Port Talbot, it doesn't seem like the ongoing fire is having a major impact on air quality in the area.

Concentrations of air-borne pollutants are currently classed as low.

However impacts of events like this can be localised, depending on your proximity to the fire and so on - and it's important to remember that the advice from police is for nearby residents to keep their windows and doors closed.

Sharon Graham, from the union Unite, said the blaze has caused "substantial damage to a vital production line".

“Measures must now be put in place to protect jobs both at Tata and down the supply chain during any period of disruption," she explained.

“Meanwhile we are asking Tata and the government to ensure that operations are rebuilt as swiftly as possible.”

She thanked the emergency services for bringing the fire under control so quickly and confirmed that no-one was injured.

The Rapid Relief Team UK (RRT), which has been providing support to the responders, has given an update this afternoon about the current situation.

In a video posted on X, one of their team says part of the building has "collapsed in" making it challenging for crews to control and contain the fire.

"A lot of the building has fallen on top trapping the fire underneath," the person adds.

The RRT says it served 150 meals to the crews on the scene last night and a further 70 this morning as work continued overnight.

Mid and West Wales Fire Service has shared another image of the scene taken at first light this morning. No obvious flames can be seen.

Contrast this with an earlier image - the third picture in our photo stack - which appears to show the same building on fire overnight. An orange glow is visible in between the metal sheets in the earlier image.

Stephanie Grimshaw, a Labour councillor in Afan Ogwr Rhondda, drove past the site this morning and says the situation seems to have "calmed down a bit".

She says she understands the concerns from residents after crews were called in April to tackle a recycling centre fire and have now been tasked with containing this incident at the Tata Steel plant.

Grimshaw says fire crews are still on the scene and urges people to stay away so they can do their job.

"While we haven't got any formal information about the cause, Tata has been keeping us updated," she adds.

Pictures from the Mid and West Wales Fire Service give some idea of the scale of the blaze overnight.

Bright orange and red flames can be seen engulfing infrastructure at the site with a hose directed towards the fire in one image.

Fire engines are also pictured outside.

Scenes at the site appear less dramatic this morning, with our reporter describing "small wisps of smoke".

But the fire service has described the incident as "ongoing".

Councillor Kellie Evans, who was driving along the road near the fire on Wednesday night, described the scene as "very apocalyptic".

She said she "couldn't see the flames because the sky was so black", adding that many drivers pulled over to look.

Small wisps of smoke can be seen rising from behind the buildings at the rolling mill end of the plant.

However these are not the thick plumes that could be seen last night.

After the heatwave last week, for most of us, waking up to the gloomy weather has been miserable.

But for emergency services, it has been a blessing - helping to keep the flames under control.

And with more rain due, external, it looks like the blaze could be extinguished soon.

On Wednesday evening, Tata Steel carried out a controlled demolition of an empty gas holder.

But the firm stresses the fire is not linked to it.

Around 14 hours have passed since a fire broke out at the Tata Steel plant in Port Talbot. Here's what we know about the situation so far:

What we know

• The blaze started at one of Port Talbot's processing lines at around 20:00 BST on Wednesday, Tata Steel says
• The company says all staff are accounted for and have been safely evacuated
• Emergency services remain at the scene, according to a statement from South Wales Police earlier this morning
• Our reporter at the scene can see emergency workers are "still busy inside the plant" but says the steelworks now look "very much like normal" from the outside
• An eyewitness driving nearby previously described the scene as "very apocalyptic"
• People living nearby have been advised by South Wales Police to shut windows and doors and avoid the area

What we don't know

• What caused the fire to break out - Tata Steel says the incident is not related to the "safe and successful" demolition of an old gas holder earlier on Wednesday evening
• Whether the fire has now been extinguished - our reporter says heavy rain through the night and this morning has cleared the smoke and there isn’t any more rising from the plant

People have been advised to avoid the area and find alternative routes as a result of the blaze.

In the last half hour, Mid and West Wales Fire and Rescue Service said they are currently responding to separate incidents at Tata Steel in Port Talbot and Neath Abbey Wharf.

"We are currently dealing with this incident, please only call 999 if lives or property are in immediate danger," the statement adds.

Earlier this morning, traffic cameras showed the M4 near Port Talbot was open but heavily congested.

However, it now seems to have cleared.

This morning, emergency workers are still busy inside the plant, but on the outside the steelworks looks very much like normal.

Heavy rain through the night and this morning has cleared the smoke and there isn’t any more rising from the plant.

There is the sound in the air of hammering and machines working from within the steelworks.

Traffic had been slowed by the smoke but is now moving freely through the area.

Extent of damage still unclearpublished at 10:15 BST

Tata Steel's site in Port Talbot is one of the largest steelworks in the world, with roughly 2,000 workers.

The company cannot yet assess the damage from last night's fire and any impact it will have on the products it makes.

Located in the east of the town, the steelworks has a vast footprint that's visible from the M4 motorway and the main railway line.

It is a heavy industrial environment with high temperatures, fuels, gases and large machinery.

Since closing its two blast furnaces in 2024 the steelworks has been in transition, with work underway to construct an electric arc furnace that will melt scrap steel.

The work of processing steel has continued in the absence of any furnaces, with hot-rolled, cold-rolled and coated steel products constantly in production.

Imported steel slabs are turned into finished products for sectors including construction, automotive and packaging.

Rapid Relief Team UK (RRT) provides emergency food and practical support to emergency services during major incidents.

It said around 100 responders were involved in an "incredibly demanding and hazardous" night of work in Port Talbot.

RRT UK volunteers arrived within 90 minutes of being called and served 125 hot meals overnight, helping to keep emergency crews supported while they continued working.

"We are grateful to every responder who attended this challenging incident," it added.

Port Talbot, in the county of Neath Port Talbot, is a town in south west Wales.

It's about 35 miles from Cardiff, and nearly 10 miles from Swansea.

Port Talbot Steelworks is a large steel factory in south Wales.

It makes steel used in things like buildings, cars and engineering projects.

The plant is currently operated by Tata Steel, which runs several major steel facilities in Europe and India.

Historically, it was a major employer in the region.

But in September 2024, the firm closed both its blast furnaces in Port Talbot, leading to thousands of job losses.

In a statement issued this morning, Tata Steel has confirmed that all personnel are accounted for and have been "evacuated from the area safely".

"Emergency services remain on site and are working with local teams to completely extinguish the fire," it adds.

South Wales Police also said emergency services remained at the site in a separate statement this morning.

Tata Steel says the incident is not related to the "safe and successful" demolition of a redundant gas holder earlier yesterday evening.
