It is a brave call but with the possibility of 4-5 inches of rainfall mentioned on the 1.30 bulletin, somewhere will cop out. Depends how the rainbands pivot. Some areas it could just rain all the time and Dorset appears to be in the firing line.
I would have caveated “could be one...”. Just like the forecasts use the words could, might, likely, just to cover themselves.

I hope it pivots further east; as it stands, the system is going to spin the rain band northwards over MBY on Sat/Sun and I'd much rather it didn't.

Just watched the BBC local forecast for the South East and it would appear there's a lot of green rain on the way. I'm off to contact Prof. Randy Cerveny to find out the mechanism which causes this rare meteorological phenomena.

Met Office has backed away from the more intense circulation hitting the South Coast, but still windy and a lot of rain. North Western France looks like it will still see some very strong winds though.

ARPEGE has wettest weather across Central Southern England from Hampshire and Dorset and NNW towards Bristol. Totals approaching or exceeding 100mm in a few spots. Somewhat different to the Met Office view.

ICON is similar although the highest totals stay near the south coast and around the Isle of Wight

WRF is closer to the Met Office solution in terms of positioning but with totals over 200mm across the high ground in the south west.

GFS also going for the wettest weather in the SW

Let's see which of the models turns out to be closest to what actually happens. Either way somewhere is going to see some significant flooding this weekend I think.

The radar returns over NW France are a classic,

Those from the Channel are definitely a thing of beauty this morning - though perhaps best viewed in the abstract

Quite agree. I woke up in the middle of the night and looked out of the window but was still almost calm. A strong ENE wind now.

I see from AIS that most of the ocean liners in Weymouth bay are in the Channel maybe to avoid the risk of ending up on the beach if the winds were too much for the anchor chains. That would be a notable story if it were to happen.

20mm and counting since midnight 

Good point. I don’t think these winds are predicted to be as strong as the last named storm, but it’s a different issue this time with the winds from the East or South East. Before the last storm most of the cruise ships took off to ride the storm out at sea, probably for the reason you mentioned.

Just checked vesselfinder.com while typing this and a number of ships have moved away.

I'm not impressed by Alex as a named storm - yes, definitely wet and windy but no more than an Atlantic depression typically delivers around the equinox.

But this is a French named storm. It certainly was a storm in north western France. 

Yes, think for us, at the moment we have been through a lot worse, but early days and the growing rainfall totals could be a big issue. Believe it was the French who named it as it was due to have more impact there.

The winds have moderated significantly here but a decent surf running into Weymouth Bay.

Some notable flooding of roads around Dorchester bypass which you might think the Council/Highways Agency would address after countless events in recent years but must be a money thing. Back in the office the suns out, well glimpses of the sun. So all in all a storm that may not warrant a name this side of the Channel IMO. But have to see what developments occur over the weekend re rainfall totals.

Looks impressive on rain radar though. 7/10 so far but subject to revision.

This is a marathon, not a sprint.

Currently, around here the ground seems to be taking the water quite well as it’s persistent, but not too heavy.

It's a bit wet here, with 11mm so far today being more than we've been used to for the last six months, but not much wind at all.

a very fine line through the Southampton area looked very wet earlier

it certainly was intense here dumping close to half inch in under 1hr. 

Amber Warning for 12:00 Saturday to 06:00 Sunday for very heavy rain.

The BBC trying to big this up, when it's just a common or garden autumn storm. Had to chuckle at this. The caption underneath reads, "Members of the Coastguard were on hand as the waves knocked a bin over"
