9.56 inches of rain in 24 hours at Bruton: 28th/29th June 1917

[Weather-history]

There was a remarkable rainfall event in the south of the UK on the 28th/29th June 1917 when a depression tracked to the south of UK and dropped an estimated 525,022,000,000 gallons or 2,343,846,400 tons of rainfall water.

At Bruton, Somerset, a rainfall gauge recorded 9.56 inches of rain, the greatest 24 hour rainfall total ever recorded until the Martinstown event of July 1955 when about 11 inches fell in 24 hours. However unlike the Martinstown event, the June 1917 event was not associated with thunderstorms although some thunder was observed.

Unsurprisingly, there was extensive flooding.

Thanks for that Mr_D. Somerton got 6.75 inches! That's just up the road from me. Hard to imagine that much falling in such a short space of time!

Those are some quite scary totals. I suppose the closest we've ever come to that here was one year to the day on the 25th June 2007. That day we had 97.8mm or 3.91 inches in old money during the 24 hour period. I cant imagine the flooding 9" of rain would give.
