At 5pm on Wednesday, the director of the service, 'Ofa Fa'anunu, said the cyclone was veering away from Tonga's main islands.
Several tropical depressions have come close to Tonga during this cyclone season so Mr Fa'anunu said people should be prepared.
"This is the seventh tropical disturbance that we've worked on this season. This is the fifth for the month of February," he said.
"All of the systems have tracked a similar track as Cyclone Pola so I'm confident people are ready for this system."
Fiji's Lau group of islands is the most likely to be affected by the cyclone on its current track.
RNZ Pacific will be broadcasting cyclone warnings from the Tonga Met Service throughout the night.
People have been advised to monitor local radio broadcasts for the latest information.
