Wales snow: Ice warning after overnight freeze
Drivers are being urged to take care on the roads following a second night of freezing conditions which saw temperatures plummet to as low as -5C.
The Met Office issued a yellow "be aware" warning for ice on Sunday after snow from Friday remained on the ground, making conditions difficult.
Gritters have worked through the night to make roads passable this morning.
Light snow is predicted for north east and parts of south east Wales during Sunday.
Travel problems are still widespread though with many main roads treacherous and some remaining completely blocked.
The M48 Severn Bridge remains closed westbound but has now re-opened on the eastbound carriageway. Both directions had been shut since Friday.
Meanwhile one lane is closed in both directions on the M4 second Severn Crossing.
Hazardous driving conditions are being reported on the M4 in both directions between junction 36 for Sarn and 38 for Margam.

The Penderyn, Maerdy, Bwlch and Rhigos roads all remain closed and are not expected to open until at least Monday. Others that are closed include:
- A4075 in Carew, Pembrokeshire, because of flooding.
- In Powys, the A4215 at Libanus, the A487 at Derwenlas, the A481 at Llanelwedd and the A44 at Crossgates because of ice and snow.
- A542 Horseshow Pass in Llangollen, Denbighshire.
The A4212 at Trawsfynydd, Gwynedd has now re-opened.
Dyfed-Powys Police is urging the public not to park on verges along the A470 to go sledging in the Brecon Beacons.
A spokesman said the parking on Saturday led to parts of the road being grid-locked for several hours near Storey Arms in Powys and a mountain rescue team was delayed on its way to a job.
First Cymru's bus services across south Wales were running to "near normal" timetables and most services in Bridgend and Maesteg are running following some disruption on Saturday.
Lloyds Coaches which serves Powys said all of its services were operating as normal.
On the railway, First Great Western and Arriva Trains Wales services were operating normally, as was Cardiff Airport and ferry services from Pembrokeshire and Holyhead.
The Met Office also had a rare red warning for snow and blizzards in part of the Brecon Beacons and Black Mountains while the rest of the country had an amber warning. Both warnings have since been lifted.
Saturday largely remained dry, and fans from Cardiff Blues and Newport County helped clear snow from pitches to ensure the respective rugby and football matches went ahead.
Cardiff and Vale University Health Board has thanked staff working over the weekend for making their own way in to work if they live locally to help ease pressure on its 4x4 service.
Meanwhile, Welsh Water has urged customers to make sure their pipes are protected from freezing in the cold weather.
Operations director Peter Perry said: "Our advice is take a few moments today and check to make sure any pipework - such as in attics, garages or running to outside taps - is adequately insulated."
