20mm yesterday and 18mm so far today from storm Alex here at stevenage.

Yesterday we seemed to be between the rain bands for most of the day, and had only recorded 4.8mm by 3.15pm.

However since then I've recorded another 37.5mm, in 18 hours. Yesterday was 16.2mm and today 26.1mm so far. It's one tip (0.3mm) off equalling the wettest day of 2020, and 38.4 is my daily record (10/06/2019), which could well be surpassed.

36.0mm so far today since midnight and still pouring

This comes on top of the 31.6mm yesterday.

So 67.6mm in less than 36 hours.

Finally over. Horrendous. Garage flooded again, also have a roof leak too leaving large patch in the ceiling 

Yes similar position here, yesterday wasn’t too wet but since last night it has been relentless. 

This morning I had to drive over to Windsor and the heaviest rain has been between here and there. Lots of flooding on the roads, with one road around Ascot not too far off becoming impassable by the time I came back. One spot in Yateley that always used to flood but has had drainage improvements done had got a lot deeper in the hour I was out. 

Blackbushe has now racked up 32mm since midnight and 67mm for the month. Before the start of October we had only had 457mm all year. 

Just hit 30.0mm here for the day, though my rain gauge seems to record less when the wind is in the east, due to its positioning. A Davis PWS two miles from here on the A327 between Arborfield and Eversley (you can see it from the road) has recorded 45.9mm so far today. https://www.wunderground.com/dashboard/pws/IFINCHAM12

My YTD rainfall total is 534.9mm. Before this month's 48.3mm so far, it was 486.6mm. That's a very average Jan-Sep total for this area, the average annual rainfall is only about 700mm and October-December is the wettest quarter of the year.

Rain has eased off for now, 33mm so far today. Forecast suggests a brief respite before another good 18 hours of rain starting this evening as the system curls back over this way. 

Indeed. I guess it's partly because the frontal system has come in from the SE (a very rare direction) so hasn't had the distance of land to the W of London to dump its moisture on before it got to the capital city.

Here the total rainfall for the month to the time of posting is 42.9mm, with 24.4mm falling yesterday.  More info in the Oct. precip. thread.

This pile of cloud on the Downs (originally posted yesterday) might have been responsible for Wiggonholt cording the highest total in the SE at 58.5mm - Wiggonholt is just over the other side of the Downs in the photo

I noticed on the rainfall radar yesterday that there was a good deal of orographically-enhanced rainfall on the North Downs.  I didn't notice it on the South Downs myself, but your report indicates that it did happen.  Again, something a bit unusual caused by the direction of approach of the frontal system.

25mm yesterday and 18.6mm so far today. Decent rain bomb so far and more to come.

10 mm so far today (since 12 am), most of that was carry-on from yesterday's rain but has stopped since dawnbreak.

37mm over the two days and 49 for the month to date .

35mm yesterday morning, and other 28mm overnight and first half of today.

Even here though, the total rainfall from this event is already up to 11.2 mm at Edinburgh Gogarbank as at 2pm this afternoon, along with 11.2 mm at the botanic gardens in Edinburgh with a lot more still to come (it is still absolutely chucking it down here as I write and if anything, the rain appears to have got even heavier here as the day has gone on).

Last 24 hours 60.4mm and 83.2mm for the month to now.

Rate has increased this afternoon and one of the chimneys is leaking!

Thought it would be too much to ask for the band to pivot further east 

Can't have the south wet and not the North West 

Lashing it down since dawn here (well, since I hit up anyway.. I don't see dawns outside of deepest winter when they conveniently tie in with my get-up time. I do love my sleep. 

Nasty day. Rain pretty much non-stop from dawn to dusk and feeling cool.

Winds eased this morning and cloud broke to produce a cool pt cloudy afternoon. Tomorrow looks like we will pull the wet blanket back across us and turn the wind dial up again.

The Thames Valley rain shield worked today. Dried out shortly after lunchtime and then dry with some sunshine until dusk.
