Work will start at the end of April clearing sand and silt at Burry Port Marina.
Carmarthenshire Council says the worst storms for many years have shipped more sand and silt into and at the entrance to the harbour, than for many years.
"It is little surprise the harbour has become heavily silted because we have even had to bulldoze, almost daily at one stage, car parks at the North Dock, Llanelli, to keep them open," said Harbour master, Rory Dickinson.
"The harbour has suffered with effects of windblown and sand laden water pouring in."
Figures will be released later this morning on the effect that last Winter's cold weather had on death rates in Wales.
Official figures are expected to be higher than last year since March 2013 was recorded as the coldest since 1962.
Last year, there were 1,300 excess deaths in Wales and almost 2,000 the year before.
Data, compiled by the Office for National Statistics, compares the number of deaths during the winter months with the average in other parts of the year.
Torfaen Council has three new gritters to help deal with winter weather. They replace older, more unreliable gritters that have become costly to maintain. The council has a total of seven large gritters and two smaller ones.
Three new snow blades, which can be fitted to the ride-on mowers, will also help clear pedestrianised areas of any snow and ice.
Pensioners in the Rhondda are being given containers of special salt to sprinkle over their paths and driveways during icy conditions.
The 'Shake The Salt' project, by the Rhondda 50+ forum and the Rhondda Rotary Club aims to make senior citizens feel less isolated as temperatures tumble.
The hope is to give out similar products for free to thousands of others who struggle to tackle steep paths and outdoor stairwells.
David Lewis, chairman of the Rhondda 50+ Forum said: "We know that not only do people slip on icy steps and break bones; the fear of slipping on icy paths keeps older people isolated at home during the winter."
So far, almost 200 containers of salt have been distributed to households.
Cwm Taf health board has tweeted to advise patients that A&E services at Royal Glamorgan are under pressure.
It has asked those with minor injuries to visit Ysbyty Cwm Rhondda instead, which is just under 10 miles away.
It comes ahead of a debate by Assembly Members later on how to prepare the Welsh NHS for another busy winter.
A debate will be held in the Senedd later on how to prepare the Welsh Health Service for another busy winter.
Last week David Sissling, the Chief Executive, revealed to the Public Accounts Committee that the service was only just catching up with the backlog of cancelled operations caused by last winter's surge in demand.
In October, Hywel Dda Health Board outlined plans to stop some non-urgent operations over winter months.
