The Met Office has issued an amber weather warning for heavy rain in parts of northern Wales and northwestern England.
The Met Office has said that in the amber warning area between 30 to 40mm of rain is expected to fall and on the high ground there could be 70 to 90mm.
In north Wales there could be rain fall of 100 to 150mm and the weather warning is in place until midday on Thursday.
Met Office Chief Meteorologist Neil Armstrong said: “A band of prolonged and heavy rain will move north and west across the UK during Wednesday and Thursday.
“Areas exposed to the strengthening northerly winds are most likely to see the highest rainfall amounts, with a chance of some areas, particularly over higher ground in North Wales seeing more than 150mm, with parts of North West England seeing more than 80mm.
“Many places could see 30-40 mm of rain, while a few areas may receive 60-80 mm. Areas over higher ground in the Amber warning areas could see the equivalent of more than one months’ worth of rain before the low pressure moves on, later on Thursday.”
