Nervous 1 NEWS' Barbara Dreaver tells of 'screaming' noise in Nuku'alofa- 'I've never experienced anything like this'

Cyclone Gita slammed into Tonga overnight, bringing destructive winds, heavy rain and a dangerous ocean storm surge.

As it happened:

12.30am: The eye of the storm is slowly passing over Tonga and our thoughts and prayers are with those suffering through Gita tonight. Please join us for continuing LIVE coverage of this developing story from 5am later this morning. That concludes our live updates for now.

11.17pm: 1 NEWS' Barbara Dreaver is in a hotel room on the waterfront at Nuku'alofa tonight. Moments ago, in a telephone interview, she said she'd covered other cyclones before, but never anything like this.

"It's screaming like a freight train and it just keeps getting nosier and nosier," Dreaver said from her Nuku'alofa hotel room.

The highly experienced Pacific correspondent, who's covered cyclones across the region, said she was genuinely feeling nervous, with her second floor hotel room flooding from rain.

She said the biggest danger for her were the palm trees or sheet metal flying through the window, and she was, at this stage, staying out of her bed.

"Compared to storms at home (in New Zealand), this just doesn't compare. It's like someone screaming out of control, the palm trees are bent over sideways, there's a lot of variables in play. Your completely at its mercy."

As she spoke, at around 11.15pm NZT, Dreaver told of hearing big bangs and things flying past the window.

"I really fear for anyone not in a concrete structure," she said.

The eye of the storm is expected to strike the main island at around midnight tonight.

10.52pm: More from Virginie Sini in Pahu, Tongatapu: "So... I feel rather safe at home but I’m about to get flooded. I could go upstairs to my landlords but that’d mean risking the open (what keeps me safe out my door is the stairs to their level) & I’m not 100% sure the roof is gonna make it throu the night."

By midnight the centre of Cyclone Gita is expected to hit the capital Nuku'alofa as a Category 5 storm.

Ofa Fa'anunu from the Tonga Meteorological service says Gita will be the strongest cyclone on record to hit the Kingdom. He is warning the public to go to evacuation centres as soon as possible.
