Open day at the Wessex sewerage plant in Avonmouth today. Came back on a bus through Andy's rain storm. Yeah, A4 (major road into Bristol from the West) struggling at about 4:30 to 5;00. See Martyn Hicks for North Bristol data. Considerable rain. Didn't see/hear lightning, - was on a speeding bus. Well worth a visit next year if you ever wondered where it all goes.
