Natural Resources Wales is urging people to prepare for the risk of further flooding across much of Wales.
It says a band of heavy rain will last into Thursday evening bringing the risk of localised flooding to all parts.
There are currently six flood warnings and thirteen flood alerts in force.
There's a 'be aware' warning of rain with 40 to 60 mm likely quite widely over high ground with over 80 mm across prone areas like Snowdonia.
To add to that there's a yellow warning of rain and high winds posted for Saturday and Sunday.
There are already stretches of road throughout the force area that are either under water, or are very wet, making driving conditions dangerous.
We are appealing to all motorists to heed road signs indicating a road is closed or flooded, as there have been examples this week where emergency services have been heavily committed, dealing with incidents where people have ignored these signs and got into difficulty in deep water
The last few days have seen prolonged rainfall.
Natural Resources Wales (NRW) is urging people to prepare for the risk of more flooding across much of Wales over the next 48 hours.
A band of heavy rain is expected to spread from the west across much of Wales from midday today and overnight into Thursday, with the worst affected areas expected to be parts of north, west and mid Wales.
It says after prolonged periods of heavy rainfall over the last few days, the ground remains saturated, meaning that further rainfall will quickly find its way into rivers and streams resulting in NRW issuing further flood warnings and alerts.
There are 6 flood warnings and 13 flood alerts in force across Wales.
NRW says officers will be monitoring forecasts closely over the coming days.
It says teams are continuing to check that flood defences are in good working order and that rivers are clear of debris which could restrict river flows.
New powers to tackle waste crime and persistent poor performers in the waste industry come into force today.
The Welsh Government says untrustworthy operators are often responsible for polluting the environment, endangering human health and causing odour and nuisance problems for the neighbouring community.
It says legitimate businesses are also being affected, who are often being undercut by such operators.
Around 94% of waste management operators in Wales are good, honest performers so there is only a small fraction of these poor performers and waste criminals that needs to be dealt with.
We have made it a priority to sort out these unscrupulous operators to ensure that waste crime doesn’t pay. The Welsh Government, together with Natural Resources Wales (NRW), Defra and the Environment Agency has worked together to identify ways to strengthen our existing enforcement powers.
There are five flood warnings and nine flood alerts in force for coastal areas around Wales.
They stretch from Gwynedd to Monmouthshire.
A high spring tide is expected tonight.
- Monmouthshire: Wye Estuary at Tintern
- Monmouthshire: Wye Estuary at Chepstow
- Carmarthenshire: Carmarthen Bay Holiday Park Tidal
- Swansea: Crofty Tidal
- Carmarthenshire: Carmarthenshire coast
- Ceredigion: Ceredigion coast
- Flintshire, Denbighshire, Conwy, Anglesey, Gwynedd: North Wales Coast
- Monmouthshire: Wye Estuary in Monmouthshire
- Monmouthshire, Newport: Usk Estuary
- Pembrokeshire: Pembrokeshire coast
- Swansea: Tidal Area at Crofty
- Swansea, Neath Port Talbot, Bridgend, Vale of Glamorgan: Swansea Bay and the Gower coast
- Vale of Glamorgan, Cardiff, Newport, Monmouthshire, Torfaen: Coast from Aberthaw to Severn Bridge
There are four flood alerts in Wales:
- Pembrokeshire coast
- Tidal Area at Crofty
- Usk Estuary
- Wye Estuary in Monmouthshire
A natural form of algae is being mistaken for sewage by concerned holidaymakers, a conservation body reports.
Natural Resources Wales says it has received reports from people concerned about sewage or slurry on the beach or in the water in places like Aberystwyth, West Angle and Pendine.
These have been investigated and found to be caused by nothing more than tiny, naturally occurring algae, called phytoplankton, that thrive in warm summer weather.
Around this time of year we do get some reports of what appears to be sewage slicks on the coast.
We treat each one seriously and whenever possible carry out tests to find out what it is.
But almost always, despite its unpleasant appearance, the 'sewage' turns out to be this common algae which isn’t harmful.

Natural Resources Wales (NRW) says nearly 600 juvenile crayfish have been released into a Powys river to replace the original population which fell victim to a pollution incident in 2012.
It says the white-clawed crayfish have been raised in the Cynrig Hatchery to replace the fish which were killed when a pesticide release affected a 2km stretch of the River Ennig at Talgarth, near Brecon.
Other species such as bullheads were also found dead in the river but it was the crayfish deaths which caused particular concern.
The white claw, Britain’s only native crayfish, was already under threat from disease, climate change, habitat degradation and competition from the more aggressive American crayfish which were introduced for food in the late 1970s and 1980s.
We’ve released 570 juvenile crayfish into a tributary of the Ennig and a further 1,000 juveniles will be released next year to replace those killed in 2012.
The fish were reared at the Cynrig Fish Culture Unit, where a crayfish conservation strategy has been in place since 2009 which aims to protect existing crayfish populations and establish safe havens for the species.
Natural Resources Wales (NRW) says work has begun to restore one of Wales' finest sand dune systems.
It says, over the last 60 years, Newborough Warren on Anglesey has lost 94% of open, mobile sand dunes as they became over-grown with grass and trees.
This destroyed the unique pioneer dune slacks necessary for the specialist and rare wildlife of the dunes to flourish.
NRW has already removed dead or stunted trees from two small areas behind the dunes.
Now it will begin the second phase of the project by removing vegetation from some dunes and cutting notches in the frontal dunes so that the sand can move about naturally in the wind. It says this will help rare plants and insects such as petalwort, sand wasps, mining bees and rare beetles that have been driven to the brink of extinction in the area.
The site needs help because the stabilised dunes are not providing the right habitat for the species that live there.
This work will allow the rare insects and plants to re-colonise the dunes and return them to naturally diverse and balanced habitats over the next couple of years.
Naturally mobile sand dunes aren’t just good for nature, they provide a more dynamic coastal defence system which can adapt to storms and sea level change. They are also fantastic natural landscapes and great places for everyone to enjoy.
Natural Resources Wales says it's uncovered a type of rare fungus previously unknown in Wales during a survey of 200 of the country’s most important bog and fen sites.
The detailed surveys of peatlands in Wales often reveal rare and unusual species and it was during one of these the team found the Fen Puffball (or Bovista paludosa).
The National Peatland Survey has been looking at the benefits of good quality peatlands to people, the economy and wildlife.
Peatland is an important habitat for nature, stores millions of gallons of water to help reduce flooding and stores carbon which helps to combat climate change.
Finding this puffball in Mynydd Epynt in Powys was an added bonus as it's the first time this fungus has been found in Wales, it is extremely rare and only five examples have ever been recorded in the UK.
Such is its rarity that that the Fen Puffball is named on the Natural Environment and Rural Communities (NERC) list as a UK priority conservation species
Natural Resources Wales (NRW) says it's taking steps to encourage salmon and sewin (sea trout) to reach their spawning grounds and improve stocks.
It says the dry September weather has been a welcome treat for most but for Wales’ fish populations the lack of rain is hindering their annual migration.
To combat this, NRW has worked with Dwr Cymru Welsh Water to release water from reservoirs into the rivers Tywi and Cleddau to encourage adult salmon and sewin to enter the rivers from Carmarthen Bay.
“The River Tywi and its population of salmon and sea trout is worth an estimated £10.2 million to the Welsh economy and the release will benefit anglers as well as boost fish numbers.........
The release of additional water from the reservoirs will not affect the public water supply and people who use the river have been alerted to take care as the flow will increase to four times its current level.
