The Bank Holiday weekend is set to come to a damp and disappointing end with most of the UK enduring more wet and windy weather.
Showers are expected over large swathes of the UK and although not predicted to be as intense as Saturday's downpours, they will be persistent and last most of the morning and afternoon.
Scotland will face the worst of the bad weather, with heavy rain bringing the possibility of minor floods, along with strong winds of up to 55mph.

Areas which have seen a lot of rain over the weekend may also experience some light flooding, as water builds up on already water-logged ground.
Among areas at risk is Daresbury in Cheshire, which has already seen flooding at the site of the Creamfields festival. The event was forced to close a day early because of the impact of heavy rain overnight.
But while it is likely to be a miserable day for most, London, the South East and East Anglia should be given a break from the rain and instead enjoy some sunny spells.

Party-goers at the Notting Hill Carnival will escape with just a few showers and even enjoy some sunny spells, according to forecasters .
Andy Ratcliffe, a forecaster with MeteoGroup, the Press Association's weather division, said: "It's going to be a windy day across the UK with rain coming in from the west first thing and spreading eastwards to most places through the day.
"It will become heavy and persistent and we can't rule out the risk of some small flooding in areas which have already seen heavy rain.
"South East England should remain largely dry with some sunny intervals."
He added: "There will be winds of 45mph in western areas areas with exposed coastal spots getting some gusts of up to 55mph."

The rain should ease off this evening and be followed by a mixed week of dry and rainy weather in the UK, as the Paralympic Games open on Wednesday.
Forecasters said the first weekend of the Games should see settled, dry weather across England and Wales.
High winds in Liverpool mean there will be no outdoor performances at the city's Mathew Street Music Festival, one of the world's biggest Beatles-inspired events.
The festival attracts around 300,000 people to the city each year. Hundreds of bands perform on five outdoor stages and in scores of pubs and clubs, taking their lead from the Fab Four who found fame after gigging at Mathew Street's Cavern Club.
Indoor gigs and performances will go ahead as planned, Liverpool Council said.
A spokeswoman added: "Due to the predicted high winds, there will be no performances taking place on any of the five outdoor stages today.
"The safety of everyone involved in the Mathew Street Music Festival is paramount, and unfortunately there is no other option.
"We are hugely disappointed, but we've had to make this difficult decision following advice from Merseyside Police and health and safety advisers.
"However, with the city's huge number of visitor attractions and many pubs and clubs with live music performances, we hope visitors and residents will continue to make the most of the Bank Holiday Monday."
