Desperate families are begging the British Government for help after becoming stranded on the islands destroyed by Irma.
And many fear they may not survive another battering from Hurricane Jose, a Category 4 storm that is due this weekend.
Kayla Laidlaw, who survived Irma as it hit Tortola described the aftermath as “truly horrific”.
She told The Sun: “Many buildings in the town are destroyed, as well as cars and boats.
“With another storm on the way, so many people are at risk and we are desperate for some assistance.”
Ms Laidlaw said thousands of people, including hundreds of British expats, are unaccounted for after Hurricane Irma wreaked havoc on the islands with 185mph wind speeds.
Haley Smit, her husband Justin and their children Lilly and Rylan are missing on British Virgin islands.
Haley’s sister told Sky News: “They went to a newer built house up in the hills which supposedly had good hurricane defences.They were with another nine people, another British family I understand.
“We were warned by them that we would lose communication through the storm but were hoping once it had passed they would be restored and we would have messages from them saying they were OK.
“But that hasn’t happened and all the families are just going crazy at the moment, sick with worry.”
Gus Jaspert, the Governor of the British territory declared a state of emergency ahead of the storm.
The British Virgin Islands, saw houses reduced to their foundations and many roads impassable in the wake of Irma, has already declared a state of emergency.
Meanwhile, thousands more Britons are trapped on other Caribbean islands.
Jenny Marie Hill, from Lancashire and her partner Anthony Broadbent say they are “trapped” in Cuba with no hope of flying home before the storm hits.
Jenny is disabled and has an artificial leg. She also suffers from lupus.
Jenny’s sister, Janine Hall said: “She has alerted the resort and there’s a doctor on site but the doctor has said he cannot get the medication and she needs to get a taxi into town.
“There’s no taxis going to town. If she runs out of meds the blood cells attack each other.
“She would have no immunity and the organs would shut down.”
Janine said that her sister only has enough medication to last one day.
Around 40 British tourists in Cuba have allegedly been told to sleep in the foyer of their hotel.
Britons are facing a challenging time getting off the island as many airports are closed and flights are grounded.
Medical supplies and other aid are being flown from the UK to the areas worst affected by Irma, following a £32 million pledge from the British Government.
The government of the Turks and Caicos Islands, which were “pummelled” overnight, declared a national shutdown as the hurricane continued its destructive path towards America.
The death toll from Irma has risen to 20 with four more people believed to have died on the British Virgin Islands, it is reported.
Forecasters said Hurricane Jose could affect already-hit areas with the British Virgin Islands on tropical storm watch, and the Commonwealth islands of Barbuda and Antigua and British territory of Anguilla on hurricane watch.
