Torrential rain in and around Honiara, the capital of Solomon Islands, over the past two days has caused widespread damage.
There is also an unconfirmed report of one death resulting from the flooding.
The director of the National Disaster Office, Loti Yates, says a depression, sitting over the country for the past two days, has caused the worst flooding in the region in eight years.
He says the Mataniko River which runs through the centre of Honiara, flooded, destroying houses and gardens.
"Just talking to the mayor of the city and he estimated that about 100 houses have been swept away. A lot of properties have been destroyed. The old Bailey bridge was under water, so yes, it has had a lot of impact on people living along the river banks."
Loti Yates says there is damage throughout the city with flooding in all the gullies.
He says many businesses and schools have been closed and there have been reports of looting.
