The Met Office has issued severe weather warnings with potential torrential downpours in parts of the UK.
Forecaster have predicted that very heavy, slow-moving showers could affect northern and Eastern England. Thundery showers should have eased up in Scotland by midweek.
The Environment Agency has also posted a “low risk” of flooding in Nottinghamshire, Lincolnshire and northern England.
Forecaster for the MeteoGroup, Aisling Creevey said “Across south-eastern Scotland, north-eastern England and parts of east Cumbria there are likely to be showers through the day, possibly merging of longer spells of rain.
“There’s also a risk of locally torrential downpours. It looks like the showers will dry out by the late afternoon and by this evening it will be mostly dry.”
Flood warning were also issued on Tuesday for the East Midlands, the East of England and parts of Cumbria.
The heavy showers throughout Tuesday night and Wednesday morning could lead to the possibility of flooded homes and roads but the risk remains low for rivers bursting their banks.
A spokesman for the Environment Agency said: “Met Office and Environment Agency staff are on 24-hour alert as slow-moving heavy and thundery showers develop over eastern and northern parts of the country.
“The public are encouraged to tune in to local media for weather forecasts for their area and to keep an eye out for signs of flash flooding.”
