A tropical disturbance is bringing damaging winds and heavy rain to much of the Pacific, prompting warnings in five countries -- Samoa, Solomon Islands, Tokelau, Tuvalu and the southern Cook Islands.
Tuvalu is still reeling from Cyclone Tino last month, where heavy swells washed across most of the country's islands, leaving half the population severely affected.
A forecaster at the Fiji Meteorological Service, Sakeasi Rabitu, said much of the South Pacific could experience damaging weather from a wide band of low-pressure.
"It's covering the whole area right from the Solomons, through to Tuvalu, Tokelau and right across to the Cooks," he said. "All a big band of this trough line, trough of low pressure, that are causing these gale winds across these islands."
Government schools in Samoa have been ordered closed on Tuesday and Wednesday as the country hunkers down for the tropical storm.
More than 130mm of rain had already fallen in Samoa by Monday night, forecasters said, which had brought flooding to parts of Apia and nearby villages and caused some rivers to burst their banks.
Storm warnings are in force for both Samoa and American Samoa, with the islands sandwiched between two tropical disturbances, and beneath a broad low pressure system.
In American Samoa, winds as high as 111km/h have been recored and hundreds of families remain without power, after lines were damaged by strong winds.
Ferry sailings have been cancelled and flights have either been delayed or cancelled.
Authorities in both Samoas are warning of possible flooding, landslides and damage caused by strong winds.
