A local youth worker Vanessa Heleta volunteering with the Red Cross says every second house they have passed in Tongatapu has either been totally destroyed or damaged by the cyclone.
She says people in the communities they are visiting are absolutely devastated by the damage and destruction to their homes.
"We are seeing shops that the rooftops have been uprooted all their goods are exposed. We are seeing floods and also a lot of branches and a lot of electric lines. We have talked to some women this morning their priorities are water, blankets and foood."
One resident in the capital Joshua Saveeti described the scene as people in his neighbourhood emerged from their shelters after what he says was a terrifying night.
The managing editor of online newsite Matangi Tonga, Mary Fonua says she has not seen a storm like this in decades.

The Director for Fiji's National Disaster Management Office Anare Leweniqila, says two islands in Fiji's southern waters in the cyclone's direct path Ono-I-Lau and Vatoa have 2500 people living on Ono-i-Lau and Vatoa.
"We hve identified two islands in the southern Lau group that will be facing a direct hit, that is Ono-i-Lau and Vatoa and surrounding nearby islands will be likely to be facing a storm wind. Those two islands are likely to be facing the cyclone, the Cat 5, the full brunt of the Cat 5 winds."
