The UK could be hit by 70mph winds and heavy rain as the first major storm of the autumn moves in.

If winds are strong enough for an amber warning from the Met Office, the storm will be officially named Aiden. 

From tomorrow, Scotland is expected to bear the initial brunt of conditions, with temperatures expected to drop to the low-single digits across the UK.

The Met Office's forecast for tomorrow says: "Band of wet and windy weather moving eastwards with heavy rain at times.”

Towards the end of the week, it predicts: "Increasingly unsettled. The most persistent rain will be across the south on Friday, with many places having some heavy rain by Saturday.

"The northwest may remain mostly dry and bright."

Vicky Mitchell of the Met Office said: “Whatever happens, we can be sure of wet and windy conditions going into the weekend.

“We can’t rule out winds of 70mph but it’s anything but certain at the moment.”

In London temperatures are expected to drop as the week progresses, with a daily low of 9 degrees forecast from Friday through to Sunday. 

Friday will also bring heavy rain throughout, with the damp conditions forecase to continue over the weekend. Temperatures are not expected to exceed 13 degrees. 

Windy conditions are also forecast, reaching highs of 15mph on Friday.
