The Prince of Wales' Countryside Fund is to donate £50,000 from its emergency fund to help farmers and rural communities in Somerset.
The news was announced as Prince Charles attended a reception at Stoke St Gregory village hall today meeting some of the organisations providing support to the region and hearing first-hand about those struggling with severe flooding as a result of the wettest January since records began.
The Duke of Westminster has confirmed he will personally match the funding and donate an additional £50,000 taking the total available to £100,000.
Prince Harry is due in Plymouth today.
He'll formally open the Royal Navy's new £30m amphibious centre at the Devonport Naval Base on Friday.

The prince will also attend a parade and reception at the centre.
The West Country has today been welcoming the arrival of William and Kate's baby son. The little boy, who has yet to be named, will eventually become the Duke of Cornwall.
And across the region people have been marking the occasion - no more so than a family from Penzance, whose latest addition was also born yesterday.
Jeff Welch has this report:
Both my wife and I are overjoyed at the arrival of my first grandchild. It is an incredibly special moment for William and Catherine and we are so thrilled for them on the birth of their baby boy.
Grandparenthood is a unique moment in anyone’s life, as countless kind people have told me in recent months, so I am enormously proud and happy to be a grandfather for the first time and we are eagerly looking forward to seeing the baby in the near future.

Camilla and Charles will conclude their three-day tour of Devon and Cornwall in Lostwithiel.
They arrived in the region on Monday and have spent their trip "waiting by the phone" for news of the royal baby.
After the engagement, the royals will head to Lostwithiel Parade Square to meet schoolchildren, members of the local community and the Lostwithiel Town Band.
Camilla is to be presented with a cake to mark her birthday and the band will play Happy Birthday to her.
The phrase "by royal appointment" probably conjures up an image of a coat of arms on a range of products and the prestige that goes with it. Well, suppliers of goods and services to the royal household, including some from our region, were invited to Buckingham Palace to meet the Queen.
