"We strongly urge people to sign up to flood warnings, keep a close eye on local weather forecasts and be prepared for the possibility of flooding.
"We also ask that people stay safe by staying away from swollen rivers and not attempting to drive through floodwater."
The agency added: "We are reminding people not to walk in flood water and not to drive through flood water because people have to be rescued and it provides a challenge for emergency services who could be deployed elsewhere and it's very dangerous."
A spokesman for the Met Office said : "Further periods of heavy rain are likely to occur across parts of northern England and north and west Wales during much of Tuesday.
"The public should be prepared for a continued risk of both surface water and river flooding during this period.
