In case you weren't already aware of how bad it was...

The floods were not due simply to the Severn getting too big for its boots but ti the tremendous amounts of rain which actually fell on or near the flooded places. What was the highest daily total on July 20th? I know that Brize Norton got 126 mm. Any others? Tudor Hughes, Warlingham, Surrey. |

Almost every significant depression in the area accumulated a lot of water. -- Paul Hyett, Cheltenham (change 'invalid83261' to 'blueyonder' to email me) |

The Severn Valley usually floods because of rain water moving downstream from Wales. What made this event so unusual was that the flood water originated locally due to prolonged torrential rain over the Cotswolds, far exceeding the amount that eventually makes it's way through Shrewsbury, Bridgnorth, Worcester, Bewdley, etc. It was an unusual and extraordinary event comparable to Lynton/Lynmouth and Boscastle, although thankfully not on the scale of the fatalities.

I remember reports of flooding in the headwaters of the Severn (Welshpool?) which were largely ignored by the media. However, the media did make the point on numerous occasions that the Severn was rising as floodwater moved downstream from 'the Welsh mountains'. It was this, coupled with the torrential rain over the Cotswolds, that exacerbated the scale of the flooding. I wouldn't compare it, either, to Lynton/Lynmouth and Boscastle. Meteorologically the two events were quite dissimilar as were the effects. -- Alan White Mozilla Firefox and Forte Agent.

I feel that the events are similar in the sense that torrential rain fell over an unusually long period in all cases and exceeded the capacity of the local geography to cope. Alan |

In the case of Lynton/Lynton and Boscastle a large quantity of rain fell in a very short period whereas in the current case a large quantity of rain fell over a much longer period. I agree that in both cases the local geography was unable to cope but in both cases the local geographies were quite dissimilar. -- Alan White Mozilla Firefox and Forte Agent.

Also in the Lynton and Boscastle floods I believe the really heavy rain, and also the flooding, was relatively localised. -- John Hall "Never play cards with a man called Doc.
