| There was a flash flooding event around the Battle Hill area of Powys (SO 0133). This is a sparsely populated area however dozens of homes were flooded by runoff flowing down the hills through properties ( not on a flood plain). 4" of rain was reported in around an hour between 1:30 - 2:30pm. Several foot bridges have been destroyed, with an old road bridge at pont-faen being seriously damaged. Flooding reported from Cradoc, Battle, Pont-faen, Sarnau & Aberbran. I have been all around the the area affected, it was fairly localised but also covered an are large enough to be in several river catchment areas. I'll write more when I have time and post more pictures up. For now, Here is a photo of the Pont-faen, courtesy of, and many thanks to David Vamplew. Many more pics later (Pont-Faen.jpg) Attachments ----------------  Pont-Faen.jpg (189KB - 383 downloads) | |||

| With so many flash flooding events around Wales and England on the 5th the event in mid-south Powys may be indicative of the day or it may be part of an isolated event...its over to the experts in that respect. Leading up to Friday the 5th Spetember 2008 the region received several wet days, with around 3" having fallen since th e1st September. The ground was Saturated. Thursday's rainfall totalled 22mm here and a similar total to the west of Brecon which shows a general rainfall pattern. Local to the Battle hill area a resident recorded 2" of rain from Thursday through to Fridday, around midday. By 2 pm the gauge, a plastic 6" measure had overflowed indicating a fall of 4" of rain in around an hour, though times arn't precise. ITV have also sourced measurements of 4" in the area. There are many EA gauges in the area along with a some meto ones at Libanus, and I believe near Talgarth (can anyone confirm please?) . I recorded 38mm here on Friday, but I was always out of the heaviest rain and the rainfall could only be described as patchy, but significantly I feel, I did record a rain rate of over 15" an hour for a very short period (30secs). The area in red on the map below denotes where damage showed significant rainfall. yellow boxes denote where properties were flooded to my knowledge - may be many more areas. Outside of that area I could see no signs of such flash flooding other than the usual debris associated with heavy rain. Talgarth had many homes flooded and roads ripped up, Felinfach had the same sort of damage(this is one of the places where the A470 was closed).In Cradoc & Battle homes that were not near streams or rivers had rivers flowing down the fields and through homes. Pont-faen had homes flooded and an old bridge severely damaged Brecon suffered flooding though I feel this is as it was at the confluence of many rivers & at the bottom of the valley. I will add some more photos & details later , though unfortunatley, one camera I used was set wrong..doh.

| In the previous set , as in this set of photos, the roads have already been cleared by JCB's - just in case it isn't obvious. These are landslides and a stone flow road     | |||

| Sam, The event was over an area that contained several river catchments, just for that reason I would suggest that it was a severe rain event...the pics that didn't come-out.. but I will get will show fields well away from the river with water channels cut out 2' or more deep. check out the map and see how many rivers are involved. Ed & ozzie, from all the local residents I have spoken too, nobody was injured, though a few helped to safety! -- photo courtesy ( and many thanks ) David Vamplew.
