Frazer Diver could be forced to abandon his belongings on the pacific island as his father fears he has been left with limited food and water.
His father Tony, from Brentwood in Essex, said his 19-year-old son texted revealing he might have to be rescued by a helicopter and taken to Suva on the south east of the island.
The teenager is part-way through a round-the-world gap year trip and had planned to leave Fiji for Australia on Wednesday after spending a week with a friend and two British girls.
He told his father last week he had been evacuated from his coastal hostel to Rakiraki inland – a district in the Ra Province on the northern tip of the main island.
His parents then faced a nerve shredding 24 hour wait for news as Cyclone Winston ripped through the island.
They then received news from their stranded son who described the scene of devastation as “damage all around them, the power off and the phone lines down”, with “food and water becoming a bit scarce”.
Mr Diver said: “They are only 19 so it is a bit of a shock for them to experience something like this.
“He was told the only way out for them is through helicopter which means they will have to leave their luggage behind, which is a big problem because they have all their lives in their backpacks.
“So it is all a bit of a nightmare for them.
“It seems like they are trapped in the hotel because the roads are blocked so they are waiting for people to come to them rather than the other way round.
“A national tragedy – they have never experienced anything like that before. I imagine they are all a bit nervous.
“My wife is very uneasy – we want to go on a plane and get out there but we can”t do that. It is very hard.
“Thankfully the storm has gone and none of them were injured.”
Mr Diver added his son was thinking of going into the Royal Air Force and joked: “If he was in the RAF he would be going into these situations rather than leaving them. It is a life experience you won”t forget in a hurry.”
