Thousands of passengers at Britain's biggest airport Heathrow face severe delays and cancelled flights due to stormy weather.

Around one in 10 flights may be cancelled at Heathrow in London due to the high winds and heavy rain that's forecast for Tuesday, an airport spokesman says.

The tail end of Hurricane Gonzalo, which caused damage in Bermuda this week, is set to arrive in Britain on Tuesday bringing gusts of up to 120km/h in coastal areas.

"There will be some cancellations, around 10 per cent of flights are affected at Heathrow," a spokesman for the airport said.

"We do not know exactly how many passengers or flights that will have an impact on, although the cancellations are only expected for tomorrow."

British Airways said it had cancelled a number of flights and advised passengers to check their bookings online.

The Met Office issued a low level "yellow" weather warning, saying the heavy winds and rain could cause local travel disruption and damage trees.

Virgin Trains said that heavy rain which was expected to start on Monday night may affect travel on Tuesday.
