Continued heavy rain and and strong winds in Solomon Islands could lead to more flash flooding and possible landslides over the next few days.
The country's met service has issued further heavy rain warnings and advised all locals to stay indoors while warnings were in place.
Director David Hiba said locals should take caution if needing to travel between islands as strong winds will affect the seas.
Mr Hiba said the weather through the weekend was expected to be rough.
He said constant rain over the last two weeks meant the risk of landslides was very high.
"We have seen that during heavy rain events, landslide is one of the big issues," Mr Hiba said.
"So basically we are asking people to stay indoors or remain at home, especially people trying to travel across from island to island."
Mr Hiba said he expected the current weather warning to be in place until early next week.
Several rivers had already burst their banks and swept through villages.
Both the Kwaibaita and Betikama rivers flooded and destroyed food gardens and crops.
Villages in the area also fear their drinking water had been contaminated.
Mr Hiba said the Ngalibiu river had swept through villages as well.
"We've had major flooding in some of the rivers, especially on the bigger islands from the New year's night," he said.
The National Disaster Management Office was still collecting damage reports from across the islands.
