The Queen has said she was saddened by recent flooding in Northern Ireland.
She sent a message of support for victims of the freak weather, during which bridges collapsed and cars were washed away in the North West.
The letter was delivered to a centre which helped co-ordinate last month's relief efforts in Drumahoe, Co Londonderry.
The Queen said: "I was very saddened to learn of the devastating flooding which has affected Co Londonderry and the surrounding areas.
"Please convey my sympathy to those who have been affected and my thanks and appreciation to the volunteers, community workers and members of the emergency services who have been involved in the response."
Residents had to be rescued from the rising flood water and cars were seen floating down the streets.
Around 100 people were saved and thousands of pounds paid out in emergency assistance.
Approximately two thirds of the average August rainfall fell within an eight to nine-hour period.
The Queen's message was addressed to Denis Desmond, the Lord Lieutenant of County Londonderry, who delivered it to the YMCA in Drumahoe.
