Storm Bronagh- Atlantic Storm 2

[The PIT]

All the attention on Helena at the moment but this feature seems to be sneaking under the radar and looks like to bring strong winds to much more of the country and much more widespread heavy rain. If it turns up could bring some widespread issues with trees generally still in full leaf.

New for the 2018-19 UK & Ireland Windstorm Season - all storms will be categorised from Category 1-5 based on expected wind gusts & severity. Met named storms, ex-Tropical systems and storms named first by other European countries all included. With thanks to @UKWX_ for graphics

 

[The PIT]

This now looking like the first storm of the Autumn as Helena weakens to much to be considered a storm. Some lively weather on Thursday with more widespread stronger winds than Helena. 

[parrotingfantasist]

Yellow weather warnings currently issued for the storm on Wednesday. Still unnamed, so I think we'll see the warnings for Thursday be issued soon or tomorrow....

[The PIT]

Yes some big storms coming and since we have a warning for 25mph gusts tonight the world will end on Sunday for us. The warning system is simply broken.

[parrotingfantasist]

Agree @The PIT . Its a bit overestimated because of its ex-Hurricane status..

 

... I wouldn't be surprised that a last minute Amber is slapped on here to the Wednesday warning for parts of NW England, N. Ireland and Scotland. Doesn't look like a nice one arriving during morning commutes and continuing for most of the day, gusting over 50mph in places. Forecasters only just talking about it now.

Now named Ali. Thread 

 

[Lauren]

So Ali isn't ex-helene?

The Uk Met Office have now named Thursday's Low Storm Bronagh 

Met Office " the storm has been named due to the squally nature of the cold front as it crosses the UK overnight – this could bring transport disruption for the morning" (Friday)

So will there be an amber warning for newcastle?

[pip22]

I think the North-west of England should have a wind warning.

We now have a yellow wind warning to go with our rain warning.

Ed. 

[Weather26]

So either the remains of Hurricane Florence or Storm Callum on Sunday then? 

[Wimbledon88]

Well according to the Irish Met Service Bronagh is the name that May be given to the weekends storm, depending on how it develops. All rather confusing. 

[The PIT]

Interesting as may or may not develop. GFS doesn't do much with it bar rain and some wind up the English channel. ECM likes it. UKMO and fax say nay as well.

that's here 

and Nick's article   https://www.netweather.tv/weather-forecasts/news/9148-uk-stormy-weather-ahead-ali-today-wind-rain-thursday-then-more-on-sunday 

[Wivenswold]

So, just to clarify. 

This is the thread for "Storm Bronagh" not the storm afterwards that was previously expected to be named "Storm Bronagh"? 

I wouldn't be unhappy to not erroneously post in an incorrect thread and cause confusion.

Who expected another Storm to be named Bronagh? Today/tonights low is called #StormBronagh

Don't know, no signs at the mo

[Wivenswold]

Back in the heady times of yesterday, there was speculation over whether Sunday would be Bronagh. I don't know, I think I need a sit down and a coffee.

[db123]

Thought storms needed amber warning to be named.   Very confusing system

Heres the rain radar

Just need to go over Britain to see it.

in the initial press release they said “A storm, (a low pressure) will be named based on 'medium' or 'high' potential impacts from wind but also include the potential impacts of rain and snow, i.e. storms will be named for weather systems which we expect an Amber or Red warning will eventually be issued by Met Éireann and/or the UK Met Office. “

so can be before we see the Amber. we'll have to wait and see how it plays out

[Wivenswold]

I think this storm is being a little understated in the press who are still reacting to yesterday's events.

From my experience in Railway ops, this one strikes at a bad time of the year and at the worst possible time of the day, while trees are in full leaf and at the start of service, in the dark. I think Greater Anglia, Southeastern, Great Northern, East Coast (LNER) and C2C could potentially suffer. Fallen leaves on damp track will also help to stuff-up the network tomorrow but I've known one broken branch to cancel in excess of 100 trains. So we don't necessarily need particularly high gusts for disruption. 35-45 mph gusts are enough. 

[Mapantz]

There's a good chance of some convective gusts developing as the cold front sweeps through later this evening, adding to already strong winds. The squally nature shows up quite nicely on the 850hPa wind speeds & direction, and also the 700hPa VV.
