Prince Charles is set to return to the flood-hit village of Muchelney in Somerset.
The visit comes five months after the Prince of Wales saw the impact of flooding on agriculture and the livelihoods of people on the Somerset Levels.
The Prince used the emergency boat service - the only means of travelling in and out of Muchelney at the time - and a tractor to meet people in their own homes.
He also criticised efforts to help those affected by the floods, saying: "The tragedy is that nothing happened for so long."
A charity abseil down the side of a hospital has been postponed due to fears seagulls would dive-bomb fundraisers.
The 100-foot abseil, down Yeovil District Hospital, in Somerset, was due to take place tomorrow to raise funds for a new special care baby unit.
But organisers were forced to cancel the event when a seagulls' nest containing baby chicks was discovered yards from the launch site during final preparations.
A spokeswoman for the Flying Colours campaign, which aims to raise £500,000 for the unit, said the event would take place once the birds had moved on.
"The seagulls are fiercely protective of their offspring, and even during the inspection the inspectors were dive-bombed by the seagulls," she said.
