Three weeks of rain could fall in just over 34 hours in parts of flood-hit Wales – with warnings of heavy downpours also in place for northern England.
A yellow weather warning covers a large area of Wales, with up to 102 mm of rainfall due over Monday until midday on Tuesday.
The warning indicates flooding to some homes and businesses is likely, transport is likely to be disrupted and there is a risk of spray and standing water on the roads.
(yellow) A yellow weather warning is in place for the North of England on Monday until Tuesday lunchtime, including the cities of Leeds, Bradford, Wakefield and Huddersfield, with a projected 66 mm of rain – a little under half the monthly average for March – due to fall.
Met Office meteorologist Greg Dewhurst said: “Through Monday it will be a fairly bright start but we will see rain spread in from the west by the afternoon.
“Then we will see heavy rain right through the rest of Monday, overnight and into Tuesday morning.”
The average rainfall for March is 138 mm in Wales , meaning the worst affected areas could be hit by three weeks of rain in just over hours.
Mr Dewhurst added: “The ground is already saturated and with all the rainfall we have had over recent weeks it is likely to lead to further flooding in places.”
Natural Resources Wales, a government agency, had no severe flood warnings and no flood warnings in place on Monday morning.
The agency had one flood alert in place meaning flooding is possible.
Wales has been badly hit by flooding in recently weeks.
