Video report by ITV Wales correspondent Hannah Thomas
Large areas of Wales have been affected by travel disruption and flooding brought by heavy rain overnight.
There are currently 25 flood warnings - with that number increasing throughout the day - and 41 flood alerts in place across the country.
Multiple bus routes across south and west Wales have been affected with roads impassable because of flood water.
Rail services are also affected, with the south Wales valleys particularly affected.
It comes a year after Storm Dennis brought severe flooding to large parts of Wales - leaving in its wake millions of pounds worth of damage to properties and businesses.
Natural Resources Wales has issued flood warnings across Wales, including in Aberaeron, Clydach, Crickhowell, Brecon, Ammanford, Aberdulais, Abercynon, Mountain Ash, Builth Wells, Carmarthen and Llandeilo.
Flood alerts are also in place across mid and north Wales, with Powys, Bangor on Dee, Llangollen, Conwy, Dyfi and Gwynedd among the areas at risk.
You can keep up to date with the latest flood warnings on the Natural Resources Wales website.
Senior meteorologist Marco Petagna said 127.6mm of rain fell at Llyn-y-Fan, Carmarthenshire, between 6am on Friday and 8am on Saturday, and 115mm dropped at Treherbert.
Mr Petagna said the average rainfall for the whole of February in South Wales was 98mm.
"So they've had more than a month's worth of rain in 24 hours," he said.
Some homes in Crickhowell have flooded, with pumps being used to minimise water.
The town was one of the worst hit areas during Storm Dennis, with hundreds of thousands of pounds worth of damage affecting residents and businesses.
Natural Resources Wales said the River Usk reached a peak level of 3.7 metres at 4am on Saturday, with that level rising to 3.9 metres by 8am. It said the flood gate at Crickhowell has been closed.
Some victims of the February 2020 flooding have only just started to recover from the damage.
A review into the response to the storm at the end of last year found increased pressure on staff operating its flood warning service hampered its ability to issue alerts to residents.
Natural Resources Wales found its operations had been "stretched" which hampered its ability to react to "rapidly escalating and unforeseen events on the ground".
It also found 12 flood warnings were not issued when they should have been, and six were issued late.
Michael Evans, Head of Operations at NRW, said it has improved its flood warning service so warnings can be issued quicker.
"We've built our resilience into the team so that we can get teams working 24/7 so that we get our flood warnings out in a timely manner."
"The real issue is with increasing climate change, the flooding risk isn't going to diminish so we are going to see wetter winters, more intense storms and more properties are going to be at risk of flooding".
NRW encourages people to be prepared for an event like this again.
"These events show that, even if flooding hasn’t happened recently or maybe in living memory, it doesn’t mean it couldn’t."
