A series of crashes and flooding caused chaos during the morning rush hour.

Journey times were doubled, if not tripled, after collisions on the M25 and the M1 leading to gridlock on roads around St Albans, Watford, and Rickmansworth.

But surface water and burst water mains also caused huge problems for motorists this morning with a number of floods, particularly across St Albans.

On the M25, there was a crash between a van and a car at j19 for Watford, with delays back to j22 for London Colney.

The M25 delays had a knock-on effect on the lanes via Croxley Green, the A404 between Rickmansworth and Chorleywood, and the A41 and then Hempstead Road into Watford.

Meanwhile, two lanes were closed northbound between j5 for Watford and j6 for Bricket Wood on the M1 after a vehicle hit the central reservation.

Numerous vehicles were spotted parked up on the hard shoulder between the junctions with some broken down.

St Albans city centre was brought to a halt too this morning.

Holywell Hill is flooded near the entrance to Verulamium Park with drivers forced to crawl slowly though the water.

Our area of Hertfordshire did not see as much rainfall as other parts of the country this morning, but it was enough to bring the roads to a standstill.

The problems came after a heavy night and morning of rainfall, with some drains unable to cope with the amount of water falling from the sky.

The rain is set to continue all morning and we could see stormy weather this afternoon.

Most of the delays have now cleared although traffic is heavy in some places still.
