A heavy rain advisory in force for Samoa this weekend as forecasters warn an active cloudband in the vicinity of the islands is threatening to cause a repeat of last month's torrential downpours. 

The heavy downpour experienced in the past few days, poor visibility, fog and slippery roads over mountain passes and ranges is forecast to continue. 

Samoa may also experience gusty winds at times and pooling near roadsides and waterways, forecasters warned. 

A Samoa Meteorological Service (S.M.S.) warning states that an active convergence zone is behind the wild weather and embedded with fresh and gusty winds as well as possible heavy rainfall.

“This cloudband is expected to remain over the islands for today causing windy and cloudy conditions with the possibility of heavy falls, gusty winds and thunderstorms from time to time,” the statement reads.

The warning comes as the S.M.S. warns of a possible Tropical Cyclone forming near Vanuatu this weekend.

Vanuatu is about 2,258 kilometers east of Samoa.

In an online social media statement, New Zealand's meteorology division warned that the storm may hit the country. 

“We’re forecasting a tropical cyclone to form west of Vanuatu this weekend,” a statement from the Kiwi forecasters posted to social media on Friday reads.

“Current computer models suggest that affects could be felt around Aotearoa towards the end of the next week.

“There is a lot to happen before then but trust we will keep you up to date”

The Vanuatu Meteorology and Geo-hazards Department also issued heavy rainfall warnings with thunders for Friday and Saturday:

“Isolated heavy rainfall and thunder expected over [Torba, Sanma, Penamaand and Malampa].

“People in these provinces are advised to take extra precaution for possible flash-flooding, landslide and coastal flooding over low lying areas and areas close to river banks.

“Remain indoors where thunderstorm activities are happening.”
