Surrprised they haven't adjusted the warnings. We are still in the warning with only forecast winds of 42mph.

It's not just about the storm but also the following showers that will accompanyed by strong convective gusts. I think they have things about right.

Battened down here on the Nw Coast of the Isle of Anglesey , winds starting to pick up over the last hour or so, expected peak gusts later this afternoon /  early evening circa 70mph + , shame its not a west to west north west flow, otherwise a day off Speedsailing at West Kirby would have been a go'er.

I really am not a fan of those overlapping warnings from the met. It just looks messy and difficult to pick out which warning area you're in.

[Marcus_surfer]

Winds Slowly picking up here no rain as of yet

[Scuba steve]

Heavy rain here in fact a thoroughly horrible day ,no wind as yet

Not much happening in Derby at the moment, although a few events that were due to take place this evening have been cancelled due to the danger to life weather warnings that have been issued/ spread on social media

[Jackski4]

This is the most boring storm ever.

The weather isn't too bad down here in South Devon, but there's some lovely cloudscapes...

Similar story in Plymouth, lenticular, asperitas all in the mix, mid level altostratus cloud making up most of that.

Every year I ask someone to explain sting jets to me,every year I understand it and every year I then forget and have to start all over again.

Hey Fiona 

I covered the recent sting jet which occurred over the western Isles Skye etc.

Sting jets can be one of the more trickier Meteorological phenomena to spot and Forecast however there have been a couple of easier ones so far in 2023 first with Poly which hit the Netherlands especially back in July 

I'm not sure if Agnes has managed to achieve a true sting jet such as the 2 events above as you really need the classical scorpions tail look.

Here we go again with my annual confusion. Is that a suggestion of a pretty little sting jet at the end, that band of dark, dry air? Every year I ask someone to explain sting jets to me,every year I understand it and every year I then forget and have to start all over again.

Hahahaha - This sounds like my brain!!

Sherkin official station in the south west Ireland currently mean wind speed of 81km/hr which is mean of 50 mph. Now that is something and falls into the Red warning criteria. This is on the coast mind you. 

 

Now see a mean of 83km Hr outside Cork,  Roches Point. Center of storm approaching Kerry, reporting 977 mb there.

RI process will get underway by 6am Tuesday 

Min pressure likely a short distance from the Southwest Irish Coast in the 970s hpa

with a slight increase as the cyclone comes onshore. Central pressure over Ireland in the mid - higher 980hpas 

Severe Rain impacts will really ramp up from 00z Wednesday through the entire day on Wednesday. I see that zone from Castletown Bearhaven across Cork further northwards into Cashel possible flooding risk extending into Dublin

 

 Further flooding through Southwest West and Northwestern Scotland 

Similar to hurricanes the Northeast quadrant will see an increasing noteable tornado risk with SRH through the roof which moves through Scotland and chances a second band forming across the pennine routes 

With the pressure actually increasing upon reaching Ireland i expect this could slightly decrease any wind impact severity. I think the extremes will be in a narrowing swathe within the Irish Sea with greatest threat to land from these speeds being the same areas of highest rain amounts running across the south Irish Coast and far Northwest Wales

This shown here perfect running the Southern > Southeast zone of the cyclone

 

 

Looks like the pressure bottomed out at 973hpa in the area I mentioned. 

From the current time is where concerns will increase as the SRH begins to intensify and the cells are beginning to take a supercellular appearance on radar 

As mentioned it is the exact same principle

All sides of a hurricane can be dangerous but the right side tends to be the most dangerous and the strongest

Literally came on this forum to have a look for comments because of the shape of those cells on radar. Scary looking!

No, it's not named after Mrs Brown, but a more consequential Irishwoman.

Actually, I had no idea the storm names were anything other than randomly chosen.

Helps if you use IR sat imaging shows moisture patterns better

Looks like plenty of planes holding around Dublin.

[mountain shadow]

And spare a thought for the passengers on this flight from La Rochelle to Cork, diverting to Birmingham. 

Not often that planes can't land at both there original and 1st alternate destination.

The only warning we have is for wind which isn't necessary this far south. Rain isn't a factor here.  The funny thing it's looking like it's going to be the quietest day of the week here.

[Thunder Snow]

Heavy rain has cleared no winds as of yet 

[Cain]

Hammering down in south wales 

[Somerset girl]

It's blustery here and a local shower . Bits of trees are on the ground as in smaller branches and it's not been  that windy here.

Just passing through here in the last hour as well, now brightening up.  Yours looks more like virga, when rain doesn't reach the ground. 

Breezy gusts here, but nothing noteworthy, expecting the peak of winds from now until midnight then calming down. 

[Ross90]

It's just rainy with a moderate breeze here, total non event unless it picks up a lot later.
