We've been hearing about how the highest-ever wind speed has been recorded in England - in the Isle of Wight - as Storm Eunice continues to cause damage and disrupt services.
There were gusts of 122mph at The Needles. Here's a look at the broader picture a little earlier.
The roof of a building containing retirement flats has been blown away by Storm Eunice.
The roof of the River View building in Ernesettle, Plymouth, was stripped away by high winds and landed in nearby gardens.

Red Funnel has praised one its captains for safely berthing one of its ferries after a video of the vessel struggling in high winds at Southampton's ferry terminal was posted on social media.
Leanna Lakes, the firm's operations director, says: “The safety of our passengers and crew is our number one priority and due to Storm Eunice, we made the decision this morning to suspend all services.
"On returning to Southampton with no passengers on board, Red Falcon approached the berth and experienced gusts of 80 knots causing the vessel to set down quickly onto the berth.
"Our highly trained captain ensured the vessel was controlled throughout and berthed safely. No damage was sustained to either the vessel or shoreside infrastructure, testament to his excellent ship handling skills."
All Red Funnel services are currently suspended.

I've just made a 50-mile trip along the south coast in a car vibrating with the shudder of the gusts, whilst keeping an eye on an angry sea to my right.
From Portsmouth to Brighton, the skies have been filled with a conveyor belt of change, from bright blue to menacing grey.
Worthing and Brighton sea fronts are mostly empty except for a steady stream of dog walkers and others, not always able to walk in a straight line.
There are fizzy drink cans rolling around the pavements and what looks like a dislodged terracotta pot shifting along the sea front.
My BBC local radio colleagues in Hampshire, Dorset and Sussex have filled their programmes with reports of trees down, minor flooding and power failures.
Looking out of my car window, I spot a couple embracing as they look out to sea, but they move on after a few buffeted seconds.
It's a struggle to stand up at Westward Ho! in Devon as our reporter John Ayres battles against the wind in a hard hat to protect himself from flying debris.
In good news, he reports that the wind has been later than expected - meaning it missed the high spring tide, which would have brought a much greater risk of flooding.
But it's still been extremely windy - people have been spotted clinging to lampposts, tiles have come off buildings, a nearby balcony has broken up, and the waves on the seafront are "absolutely enormous".
Image source, PA MediaTrain services to and from London Waterloo have been suspended amid the worsening weather and reports of scores of fallen trees blocking the tracks in the Wessex area.
All services that are mid-journey will be brought to a stop at their next station.
We don't yet know how long this suspension will last but are told it will be in place until at least mid-afternoon.

Do not put yourself at risk to take selfies during the storm, warns James Instance from Cornwall's Falmouth coastguard.
"Your life is not worth a photograph," he says.
Speaking to the BBC, he stresses that the vast majority of people who get into difficulty in the water never meant to get into the water in the first place.
And he advises dog-walkers who are anywhere near the coast to keep their pets on a lead.

Before the pandemic, school being closed for the day might have meant a day off for pupils.
Not any more. Well, at least not for everyone.
Both staff and children have become used to working remotely, having had no choice but to adapt during lockdowns and more recent closures related to teacher absences.
Letters have been sent out to parents advising that children can find work on remote learning environments.
One primary school in Wokingham asked Year 2 pupils to "look at your class Teams page for online work".
"Have a happy half term," it added.
The impact of Eunice is now widely being felt across the country with strengthening winds across southern parts and heavy snow impacting many areas of the north.
These photos give a sense of conditions across the UK.
