People in Wales have been warned to brace themselves for flooding and disruption as the next band of heavy rainfall approaches.
The principality was given a taster of Monday's forecasted big storm last night as strong winds swept in westwards - resulting in ferry services being cancelled as well as speed limits on the M4 being reduced to as low as 40mph.
But more yet to come as o fficials from the Welsh Government's Natural Resources Wales say rainfall totals of up to 60mm over a short duration overnight could lead to flooding from surface water and rivers.
A spokesman said: "While all of Wales can expect heavy rainfall, the worst affected areas are likely to be Powys, Denbighshire, Flintshire, and Wrexham.
"The rainfall is likely to be accompanied by strong winds, which combined could cause localised flooding with fallen leaves, branches and debris causes blockages in drains, streams and rivers."
Strong winds expected late Sunday and during the early hours of Monday morning could also cause large waves along the Pembrokeshire and South Wales coasts.
And with sea spray along coastal paths and coastal roads expected, people have been advised to take extra care.
"Officers have been monitoring river levels closely and checking flood defences over the weekend and will continue to keep a close eye on the situation," the Natural Wales spokesman added.
"Staff will be on standby to deal with incidents and to remove any blockages in rivers which may pose a flood risk."
People have also reminded that flood water can be "extremely dangerous", and are urged not "to walk or drive through it" unless instructed by the emergency services.
Council officials in Rhondda Cynon Taff said their staff were doing everything possible in preparation.
Cabinet member and councillor Andrew Morgan said local authority staff had been filling lorries with sandbags and additional chainsaws had been acquired in the event of any falling trees.
"There are also additional crews standing by to cover the call centre if we have a large volume of calls for assistance," he added.
Also, utilities firm Dwr Cymru Welsh Water has asked customers to work with them to keep sewers flowing through wet weather.
Company director Steve Wilson said: "Our engineers will be on high alert to respond to any issues which may occur on our wastewater network.
"The network does get placed under increased pressure during this type of weather. Therefore, we would be grateful if customers could immediately notify us on issues they become aware of relating to it in their area via our 24 hour helpline."
