Amber weather warning for rain affecting North Wales
Heavy rain could bring flooding to parts of North Wales
An amber weather warning has been issued for parts North Wales as forecasters say heavy rain could lead to flooding.
It's in place until midday on Thursday.
A lesser yellow alert covers the rest of North and Mid Wales through Wednesday afternoon until 0600 Thursday morning.
Met Office meteorologist Alex Burkill said: "Some areas are really going to see a lot of heavy, persistent rain through a big chunk of Wednesday. It is going to be a pretty wet picture as we go through the rest of the week for many places.
"There is some uncertainty as to exactly where we are going to see the heaviest rain and where is most likely to be impacted."
The forecast says heavy and, in places, prolonged rainfall is expected from an area of low pressure arriving from the east, which has brought downpours to parts of central Europe.
Many places could see 30-40mm of rain, while a few areas may receive 60-80mm as heavy rain moves northwards throughout Wednesday. The Met Office said there is a small chance a few upland areas could see up to 150mm.
In addition to the thunderstorm warning, which also includes scattered showers and the threat of spray on the roads and sudden flooding, the south of England could see heavy, thundery showers which could bring 30-40mm within three hours.
A Met Office spokeswoman said: "The precise track of the low pressure which would determine where the rainfall comes is still uncertain and is something we are keeping an eye on.
"We would encourage people to keep an eye on the forecast over the next couple of days to see how that evolves."
