The British public have helped raise £1.3 million for the victims of Hurricane Irma in the space of a week.
More than £650,000 has been donated to a British Red Cross Appeal, with the UK Government matching every pound.
The Government has pledged to match donations made by the public until the private donation total reaches £3 million.
The British Red Cross said it is providing drinking water, family hygiene kits, blankets, tarpaulin and other emergency supplies across the islands affected.
It has also sent six experts to help with the emergency response.
An estimated 1.2 million have been affected by one of the most powerful storms ever to cross the Atlantic.
It hit more than a dozen Caribbean nations and island territories, and claimed at least 40 lives.
The Red Cross has set up a family links service for people worried about relatives in a British Overseas Territory.
People can search a list of names or register their relatives' details while individuals caught up in the hurricane can register as being "safe and well".
International Development Secretary Priti Patel said: "The overwhelming generosity of the British people provides hope where there is despair, and by matching pound for pound public donations to the British Red Cross Appeal the Government will double the difference Britons can make to the lives of those affected by Hurricane Irma."
