Looking at the rain radar, there has been a fairly persistent 'tail' of
heavy rain running down roughly through Basingstoke, Winchester, Chichester
kind of area, and a few miles out to sea. A friend who lives in Bosham is
unable to drive to work in Portsmouth due to flooding, and is looking
nervously at the very full mill stream running past his house. Any idea why
this belt of heavy rain has been rather stuck over the same area for hours
instead of moving across the country, as the rest of the rain in the South
seems to be doing?

Cheers!

John.
