The King has expressed his 'profound sadness' at the destruction and loss of life caused by Hurricane Beryl in the Caribbean.
In a personal message he sent his 'heartfelt condolences' from the Royal Family and praised emergency services personnel and volunteers who are working round-the-clock to deal with the aftermath.
It is understood His Majesty is additionally making a substantial charitable donation to the disaster recovery and relief efforts.
He has asked to be kept closely informed of the developing situation, and is hoping to engage with regional leaders directly in coming days to offer his support and sympathies.
In his message King Charles said: 'My family and I have been profoundly saddened to learn of the dreadful destruction caused by Hurricane Beryl across the Caribbean. Above all, we send our heartfelt condolences to the friends and families of those who have so cruelly lost their lives.

'I have seen the extraordinary spirit of resilience and solidarity that people across the Caribbean have shown in response to such destruction - a spirit which has been called upon too often - and so I also send my particular gratitude to the emergency services and volunteers who are supporting the rescue and recovery efforts.
'At this most difficult of times, please know that our most special thoughts and prayers are with all those whose lives, livelihoods and property have been so utterly devastated.'
Hurricane Beryl has battered several islands in the Caribbean, most recently Jamaica, killing at least eight people.
Almost every home has been destroyed or badly damaged on Union Island in the Grenadines, where officials say the storm has caused 'immense destruction'.
King Charles remains head of state in St Vincent and the Grenadines, as well Grenada, which has also been badly hit, and Jamaica.
No storm has reached Beryl's level of intensity so early in the hurricane season, which runs from June until November.
The King's message comes after it was confirmed that the Prince and Princess of Wales had donated privately to the relief effort and continue to follow the impact of the hurricane closely.
