Good mornng, Here is what you need to know before heading out on your commute today.

On a day which promises nothing more than overcast skies followed by heavy rain this afternoon, you're best bet may be to stay inside.

But if you are out this morning, be aware of very heavy traffic anti-clockwise on the M25 from j20 for Kings Langley all the way round to j15 for the M4. It is very bad from j17 for Maple Cross.

Queues worse than normal on the A41 southbound between Two Waters Road, near Apsley, to the M25 roundabout with queues too on the A4251 from Kings Langley to the same roundabout.

Heavy already on the A405 between Chiswell Green and Bricket Wood.

Queues on the A1 London-bound approaching Stirling Corner and then Apex Corner, near Borehamwood and Mill Hill. Queues too on the A411 between Borehamwood and Elstree.

Delays on the A10 southbound approaching Church Street in Edmonton because of an incident.

Slow on the M11 southbound between the M25 and the North Circular.

Rail
