Floods worry warns environment agency as rain forecast
Environment Agency Wales has warned of possible flooding with heavy rain forecast for more than 24 hours from Sunday evening.
Drainage systems may not be able to cope with downpours forecast to start in south and west Wales and move north east during Monday, it has warned.
The agency said some streams and rivers could burst their banks if hit by localised downpours.
The Met Office warns of bursts of rain overnight with it becoming very windy.
Environment Agency Wales said low-lying agricultural land and some roads may be affected by any heavy rain and is advising people in rural areas to take precautions.
It said: "The main concern is for drainage systems being unable to cope with the rainfall forecast by the Met Office which could cause some localised flooding and surface water on roads.
"Officers will be monitoring river levels as they could respond if the rainfall continues and Flood Alerts and potentially Flood Warnings may be issued."
The Met Office warned that rain will slowly spread east in Wales and become heavy through Monday, with localised flooding possible.
The rain is only likely to ease by late evening and it will be very windy all day.
