The worst of the category 5 storm has now left the Pacific Island nation, but not before at least five deaths, wind gusts of 325km/h and 12m-high waves.
Alexis LewGor said her whole family lived in Lautoka.
They were safe but she had little sleep on Saturday because she was worrying about them.
"I was able to talk to them through Facebook, my main concern was that if anything happened to their houses they were able to go somewhere for shelter," she said.
"Considering all the other natural disasters in the past, all you can do is wait it out.
"My sister said it was 'fast and furious', and was all over in two hours. She said the wind was 'very frightening' and you can't sleep through it because you don't know what will happen," Ms LewGor said.
She said her family described scenes of devastation.
"There are broken trees and rubbish everywhere, there is no power, but thank God we were still able to communicate. Everyone's okay, my whole family.
"I'd hate to see what it looks like and there will be a big clean-up, but they are very resilient and they will just get on with it.
"When I grew up there 150km/h [wind] was bad, but 350km/h is just so much faster."
