The Met Office has updated its weather warning from "yellow" to "amber" in London and the south as Storm Doris hits the capital .

There are high winds and heavy rain throughout London , causing disruption on rail services and delays and cancellations at Heathrow Airport.

The Met Office is also warning of winds gusting at speeds of up to 80mph in the London and South East England region, saying the storm has rapidly deepened, making it a "weatherbomb".

London Fire Brigade said it has attended six Storm Doris incidents so far today (Thursday, February 23), including one call in Chiswick which saw a tree fall into a house.

Heathrow Airport says around 10% of its flights will be cancelled as a result of the weather, while speed restrictions are impacted Network Rail and Southern Rail .

Meanwhile, away from Storm Doris, there were also delays on the London Overground caused by a signal failure which meant there was no service between South Acton and Richmond, and severe delays between Stratford and South Acton/Clapham.

The same signal failure also resulted in the part suspension of the District line between Richmond and Turnham Green.

Issuing its amber alert which is running until 8pm, the Met Office says “some very strong winds are expected on Thursday in association with storm Doris with gusts of 60-70mph likely, and 70-80mph on coasts and hills”.

It continues: “Whilst the strongest winds look to be only short-lived, damage to structures, interruptions to power supplies and widespread disruption to travel networks are likely, with a danger of injury from flying debris.

"Trees are also likely to be damaged or blown over.

“Heavy rain is also likely through Thursday as well as some snow over high ground as the system clears eastwards. These may prove additional hazards."

It said a deepening of the storm had made it a "weatherbomb", which means winds will be strong enough to cause structural damage and blow over trees.

Network Rail has put in speed restrictions as has Southern Rail, and the RAC has also warned drivers to take extra care on the roads .

“With Heathrow operating at more than 99% capacity, there are no gaps in the schedule that can be used for delayed flights and as a result, some passengers may experience disruption to their journeys today.

“Passengers should check their flight status with their airline before coming to the airport.

“As always, Heathrow’s top priority is the safety of passengers and we apologise to those whose travel has been affected.”
