34mm of rain since 9am yesterday and local river flooding, definitely not standard!

I note that down here in the south the Amber warning still only talks of maximum of 60-80mm. I suspect this would have only be a yellow warning  it wasn't for the fact that the ground is already highly saturated, but with swollen rivers and saturated ground the flood risk is higher so the impact riak of 60-80mm is higher. 🙂

I see a wind warning popped  up in the South West this morning  - hope it doesn't extend further east - frankly I've had enough of it !


As an aside, I think the MO needs to  take a look at its warning map. In cases of multiple and over laid    warnings it's difficult to see what's what and where !

50-60mph gusts are very typical coastal wind speeds during an atlantic storm, nothing exceptional, and won't be remembered.  


Rainfall has still only seen 26mm here since it set in yesterday - over 24 hours ago!!

Neither of those are at all normal, as in Kent we usually just see fronts zipping through, with only a few hours of strong winds each time.


There have been stronger winds in years past, sure, but these were around a 1 in 5 year event in terms of strength. In terms of longevity, they'd have a much longer return period.

As for wind  coastal northeast england sees at least one storm of 60-70mph winds each year. 


Also for Shoeburyness the top wind gust from Dennis was only 60mph and only 8 hours with winds gusting of 50mph or higher, and those 8 hours were split. So i suspect a little over exaggeration going on.

And we're talking about both storms, note the "continued" bit in this very thread's title. The combination of Ciara and Dennis is noteworthy here.


https://www.iossc.org.uk/weather/?sn=cam1


is the source I use. It's still a fair way off, but at least the coastal aspect is the same. I would have to take issue with your "only 8 hours of 50mph" too, as if it's something piddly... it's not! Maybe for you south-coasters it is, but here in the sheltered north it's noteworthy.


I could also go on about how we don't normally get trees down locally each winter, nor do we get gable ends of buildings collapsing each winter either, nor does the ground get so soaked that you can see the water with every step on the lawn.


I accept that for you it was unexciting, dull, run-of-the-mill, whatever. Here, and for a good chunk of the country, it was noteworthy.

In Edinburgh, although we've not had anything like the poor people of the Borders and various areas in England and Wales it is windier than yesterday. Gusting to 54 mph recently but with only 12mm of rain in 48 hrs. Heavy showers approaching and I think we will feel the 'sting' tonight as Dennis runs past to the north

Does anyone know what is actually going on in the Borders, I hear that part of Galashiels has been washed away, but seen no media confirmation. I live only 10 miles from the Borders and Dennis has produced about 10mm rainfall and the same westerly force 4 we have endured for the past 10 weeks! It's been quite sunny and dry here today.

That of course, comes less than a week after that incident at the guest house/restaurant on the confluence point where the Slitrig Water runs into the River Teviot at the peak of Storm Ciara.


This led to the side of that building collapsing into the river and as a result, that building will now probably have to be demolished and is already condemned. Luckily, none of my family who live down there are in a location where they are directly affected by these events themselves, but I can only imagine that this must be a horrible time for a lot of individuals and businesses down there, especially with Storm Dennis having arrived so soon afterwards.

As far as I am concerned Storm Dennis has been a big weather event. Site traffic suggests that is the case as does the footage of the horrendous flooding. I know things have been made worse because the water table is already high but that makes not a jot of difference to  those who have had their homes ruined.

Also,  I don't think you can separate the 2 storms or the cumulative rain totals this winter.   All are caused  by the same underling  conditions (strong jet  being driven by an extraordinary temperature gradient).   Then there is the issue  that we are having  another exceptionally wet and windy winter  only 5 or so  years for the last lot.  Time will tell if this is going to become the new norm - if so, there is going to have to be a lot of re-evaluation in  terms of flood protection and building construction methods.

That was a potent little squall line that came through here just then. Clear skies followed all of a sudden by heavy rain and a potent wind which has made the house rattle. Looks like there has been some lightning over the Peaks as well.

Today there was a definite big downpour and squall around 8.00 am and heavy rain most of the day amounting to 23.5mm which is a lot for here but something I would expect in a day most winters.


The mildness at 13.9C was the most notable thing really.

My thoughts go out to those with floods!


Today our river has been at its highest since 2007 when it flooded for the first time in my life.  Thankfully it stopped raining this afternoon and the level stopped rising, so it only managed to puddle onto the main road bridge but not enough to close it like last time.  It’s not that we’ve had a great amount of rain today but, as already mentioned, the water table is high from previous rain.

Just to add that around here a number of fences and trees were brought down last night and today. This morning the road through the centre of town was blocked for several hours by a fallen tree. Had the time of day been different it would very probably have crushed a car.

Yes here too escaped the worst a wet windy weekend but nothing unusual here total rainfall over weekend 27mm was expecting double that after Amber warnings for the South downs and Weald Friday suggested maybe 100mm. Chris Fawkes just now mentioned Brecon Beacons have had a phenomenal 169 mm over weekend

Like last Sunday evening, just drove to Southend sea front. As we got there, the wind picked up suddenly and was stronger than last week. So much so with trees and lamposts bending back and forth, we decided to leave as it did not feel safe.

If you look closely at the latest rain radar maps as well, you will also notice that a band of rain is now approaching here from the NW, so this could well be a very lively night ahead indeed on more than one front (if you get the pun here).

Rainfall here for the past two days totals 40.4mm, which is the best part of a month's worth.  So its not surprising that the upper Medway valley is flooding, with some blocked roads.


As I mentioned in an earlier post the A21 Tonbridge bypass is closed for 10 days for repairs, and the traffic diverted through the town is horrendous.  The cut through the lane from south Tonbridge to Leigh is closed because the flood barrier is in operation, next upstream two roads into Penshurst are cut off by floods, and so is Chiddingstone.  To get back from Sevenoaks (normally a 15 minute journey) took me 90 minutes as I went on a great circular trip through Hever, Cowden and Ashurst.

Latest wind gusts at Edinburgh Gogarbank as at 11pm tonight, now up to 58.4mph from the SW with a mean wind speed of 33.6mph. If my memory serves me right, that makes today our windiest day of this winter.

This means that whilst we haven't had anything like as much rain from Storm Dennis as what we had from Storm Ciara, it is Storm Dennis which is now giving us our strongest winds.

The forecasters in the run-up to this event were saying that there would be a bit less wind from Storm Dennis, but with rain being a bigger issue than was the case with Storm Ciara.

That may well be the case down south (which just goes to show how England-biased these forecasts often are) but as far as this part of the world, they have completely got that the wrong way around and to me, there should probably have been an amber warning for wind in place for tonight's wind event in this part of the world, instead of the yellow warning for that which we are currently under.
