Good morning!

Here's your update for Tuesday's commute.

Weather

It's warming up today with a sunny start and highs of 24C. But this evening, while remaining hot, will see showers and possibly even thunderstorms bring down the temperature slightly.

Tube and train

There are severe delays on the District line between Tower Hill and Richmond/Ealing Broadway due to a signal failure at Bromley By Bow, and further delays on the whole of the Hammersmith and City line for the same reason.

Thameslink trains through St Albans have minor delays.

There's a good service on Network Rail, London Midland, Southern and East Midlands trains.

Traffic

The M25 is experiencing delays anticlockwise at junction 21A  in Potters Bar, junction 20 for Kings Langley and junction 18 at Rickmansworth Road.

There are severe delays of up to 15 minutes on the A1 Barnet Bypass heading southbound towards Stirling Corner, and further queues on the A1 Watford Way in Mill Hill at T A1 Archway Road southbound between the A1 and Acorn Terrace.

North Circular Road eastbound in Brent Cross is slow from Neasden through to the M1 intersection, and further along the road in East Finchley.
