One flood warning and nine flood alerts remain in place across Wales.
Arriva Trains Wales services are affected between Chester and Crewe.

In a statement, it said: "River levels are above normal but flooding of property is not expected at the moment.
"River levels at Manley Hall have reached their peak. In addition to the area detailed, some localised flooding problems may result from surface water.
"More rainfall is forecast overnight which may cause the river to rise."
On Monday, heavy rain earlier caused travel disruption across Wales with parts of north east Wales saw a month's worth of rain fall.
Fire services in mid, west and south Wales reported no flooding incidents since Monday.
BBC Wales weather presenter Sue Charles said some heavy and possibly thundery showers are expected across Wales on Wednesday but should move south leaving it brighter.
"The rain clears tonight with a few showers lingering early on Thursday, but it will be generally drier with bright spells, feeling fresh in a cool northerly breeze," she added.
