North Wales at risk as month's rain set to fall.

MORE than a month's rain is expected to fall in two days in parts of the UK this week, the Met Office has warned.

The forecasting body has issued amber warnings - the second most severe alert - for heavy rain to include much of central and England, with parts of Wales also affected by downpours.

Much of Wales could see heavy showers through today and tomorrow, with the rain falling on already saturated ground in many parts.

That could cause localised flooding and dangerous driving conditions. But the Met Office said it was unable to pinpoint exactly where the worst rain will fall because the picture is so changeable.

A low pressure area is bringing with it moist, warm air from the continent - with the possibility of torrential, sometimes thundery downpours as well as prolonged periods of rain.

A statement from the Met Office's chief forecaster said: "An area of low pressure will move westwards across southern Britain from the near continent during Friday. As it does so it will draw a plume of warm moist air westwards across many parts of central Britain.

"This is likely to bring some very heavy and locally thundery rain during Friday and lasting into Saturday as it moves north.

"Through the whole two-day period, 20mm to 40mm of rain is quite likely with as much as 60mm to 100mm possible in places, particularly on upslopes of northern England.

"With the ground being saturated in some areas, these amounts of rain are likely to cause problems. As is usual in this type of situation there remains uncertainty as to which areas will be worse affected."

The Environment Agency Wales warned of possible disruption and flooding in North, West and Mid Wales.

A statement said: "River and surface water impacts are likely such as flooding of land, roads and properties. There may also be some travel disruption."
