Flooding has caused travel disruption, after heavy snow in south and mid Wales led to some roads becoming impassable.

A Met Office yellow weather warning for snow was issued for 11 of Wales' 22 counties, but ended at 10:00 GMT.

Traffic analysts Inrix warned of hazardous driving conditions on some roads in Powys, Ceredigion and Neath Port Talbot, but no schools had to close because of the snow.

Natural Resources Wales also issued a flood warning for the River Teme at Knighton, Powys.

Transport for Wales said flooding on the railway between Gloucester and Lydney was causing disruption to trains between Gloucester and Cardiff Central.

Trains could be cancelled, delayed by up to 40 minutes or terminated at Gloucester, it warned.

Meanwhile, the A466 between the A4136 in Monmouth and the Newland turn off in Redbrook has been closed in both directions due to flooding.

The rain warning is in place in Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Powys, Rhondda Cynon Taff, Swansea, Torfaen and Vale of Glamorgan.

Snow caused problems on the roads after falling overnight.

Some vehicles were left stranded on the A4109 between Seven Sisters and Banwen in Neath Port Talbot, while the A482 in Lampeter, Ceredigion, and A4221 between Abercrave and Coelbren in Powys were blocked for a time.

BBC Wales weather presenter Derek Brockway said "a huge swirl of low pressure" was causing the unsettled conditions.
