Inrix, which analyses traffic data, said in an alert: ‘Road closed and stationary traffic due to serious crash, a car and a motorcyclist involved on M25 clockwise from J25 A10 Great Cambridge Road (Enfield) to J27 M11 J6.’
Congestion is building up in the area, with queues beginning to stretch back towards junction J24 near Potters Bar.
The crash comes as heavy downpours have hit London and the south this afternoon.
And the weather has more in store for the region tonight.
The Met Office issued a yellow weather warning for strong winds, which is in place from 8pm tonight.
The forecaster said: ‘The winds will be strengthening this evening and into tomorrow with gusts up to 60-70 mph along exposed coasts.’
Drivers were told off yesterday after impatient motorists tried to turn around at a road closure during a medical emergency.
This meant that when the road was ready to open, traffic release was delayed for everyone because cars were ‘facing the wrong way,’ National Highways said.
Footage also showed several drivers stepping out of their vehicles and hanging out on the hard shoulder, a common sight during motorway closures, which is advised against as emergency vehicles might move past suddenly.
