Brits have been told to avoid large bodies of water as concerns grow over further flooding.
Yellow weather warnings are in place for large parts of Wales and northwest England on Tuesday as heavy downpours are expected to fall on already wet ground.
The Met Office said "persistent heavy rain may lead to some disruption" in the morning, including delays from spray and flooding on roads, impacts on bus and train schedules and even some flooding of homes and businesses.
Rainfall totals of 60-80 mm could also accumulate over parts of Cumbria, according to the national forecaster, with "heavy and persistent" downpours also anticipated in Wales.
It comes after Mid and West Wales Fire and Rescue Service service urged members of the public to avoid wild swimming and other water-based activities after a second woman was found dead following an incident at Ystradfellte waterfall in the Brecon Becaons.

A tweet from the fire service on Monday read: "The popularity of outdoor water-related activities, such as open water swimming and stand-up paddleboarding, has grown in recent years."
"However, the Service urges people to avoid taking part in such activities following recent spells of heavy rainfall and during a weather warning.
"The risks of entering open water include strong currents and cold-water shock, as the temperature can be much colder than anticipated, especially in fast-flowing sections."
