It said: "There is a good chance driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times by car and bus.

"Delays to train services are possible. Some short-term loss of power and other services is likely."

In the past, these alerts have led to some local parks, including the Royal Parks covering Richmond and Bushy, to enforce partial closures.
