Why show a weather forecast for Oxford instead of Datchet? Flooding in Datchet is determined by the rainfall in the upstream catchment of the River Thames. Oxford is roughly in the middle of the upstream catchment and so the rainfall forecast there is a better indicator of future flooding than a more local site. It takes 2-3 days for rain in Oxford to reach Datchet.
