The Met Office has issued a yellow warning for heavy rain.
The warning is in force through Wednesday until 6 am on Thursday 23 May.
The warning states:
An area of rain is expected to develop across eastern and central England and then move northwestwards to affect northern England and north Wales during Wednesday afternoon. The area of rain could then become slow moving, heavy and persistent, especially over north facing hills, before clearing during Thursday morning.
There is a lot of uncertainty over exactly where the heaviest rain will occur and this warning is likely to be updated. Many places will see 30-40 mm of rain, while a few areas may receive 60-80 mm. There is also a small chance that a few upland areas could see much higher totals, in the order of 100-150 mm.
