My point really was the warning should scroll with the forecast timeline, not a centred banner. Then whatever point in the 5 day forecast you were looking at, the start & end points of the warning would be correct. Multiple warnings would add a layer of complexity, but not that difficult to solve.
Not much rain here so far, just enough to deter me from some daily exercise! There could be some interesting totals further north.
Roll on Spring and the start of Cornwall's dry season! It's interesting how much more seasonal rainfall is here, than even up at Wootton Bassett (it wasn't 'Royal' then, but ultra conservative) during the my period there in the late '70s / 80s.
