Twenty-nine-year-old Tom Bourdon was feared missing after the cyclone swept through the country.
He had been unable to make contact with his family since Thursday when he boarded a bus in Amapura for an overnight journey to Rangoon.
Up until then the former Cavendish School pupil had been in regular contact with his family and girlfriend Paloma in the month he had been travelling abroad, which he paid for with prize money he won in a national photography competition.
His parents, John and Avis, brothers Peter and Daniel and sister Rachael, had spent the week anxiously waiting for news at the family home in Rossington Close, Eastbourne, and had made appeals for his safe return on national radio.
The family had also been in touch with British embassy officials in Burma who were trying to trace him.
Thousands of people are feared dead and thousands more missing since high winds and a severe storm surge swept through the country.
On Wednesday afternoon Tom's sister Rachael said they had received a brief email from him to say he was alive and well in Burma and trying to get a flight to Bangkok in Thailand.
"We are absolutely delighted," said Rachael, who works at the Hydro Hotel in Eastbourne.
"I have had a very short email just saying he is okay and hoping to get a flight to Bangkok. We are all so relieved."
Tom, who attended Park College and worked at Eastbourne College of Art and Technology, moved to Spain a year ago and had been working as a carpenter.
A keen amateur photographer, he was awarded the top prize in the highly prestigious Wanderlust Professional Travel Photo of the Year Competition 2008 with his portfolio of five images from a Hindu festival.
