Extensive flooding in Gloucester forced the M5 to close on Monday morning.

While the M5 and M50 were built as fast roads, the valleys were a tougher challenge.

Likely traffic hotspots include the M4/M5 interchange near Bristol, sections of the M25 around London, the M5 and M6 in the West Midlands and parts of the M60 in Greater Manchester.

On Thursday, the monitoring group said the rebels had cut the M5 highway between Aleppo and the capital Damascus near Zarbah, 15km south-west of Aleppo city, and taken control of the interchange between the M5 and the M4 highway further south, near Saraqeb.

Tamzin Hall, 17, from Wellington, Somerset, sustained fatal injuries when she was struck by a car on the M5, between Taunton and Bridgwater shortly after 23:00 GMT on 11 November.
