Valid from 0005 hrs to 2359 hrs Tue 27 May 2014
The Met Office warning says: "A prolonged spell of rain, heavy at times, is expected to affect parts of eastern England during Tuesday. The public should be aware of the potential for disruption, particularly to travel, and possible localised flooding."
Chief forecaster's assessment: "A frontal zone developing over the Low Countries will start to spread westwards into the UK in the early hours of Tuesday morning.
"This frontal zone is then expected to linger over parts of eastern England on Tuesday giving a prolonged spell of rain which could see some eastern parts here seeing more than 40 mm of rain in 24 hours."

The forecast is for heavy rain to clear eastwards then brighter skies developing. Many parts dry for much of the day but showers will develop, these heavy, perhaps thundery at times and quite slow moving, giving a risk of local downpours. Maximum temperature 10°C.
