The Samoa Meteorology Service is forecasting more rain overnight and has warned the public to be cautious as it could lead to flooding in vulnerable areas.

The S.M.S. Principal Scientific Officer [Climate Services], Faapisa Aiono, said the public should be aware of potential impact and to stay vigilant when driving on roads as there would be heavy downpour that would lead to poor visibility, gusty winds as well as foggy and slippery roads. 

"Be aware of possible flooding in vulnerable and river areas," Ms. Aiono said.

"There is a possibility rain may ease tomorrow towards the evening if current model predictions are consistent. 

“The low pressure that is currently influencing our islands is anticipated to move south-eastward while weakening within mid-week.”

Asked if there will be any flooding, Ms. Aiono said: "No report yet of flooding from the general public but if current conditions prolong then flooding is most likely to occur in vulnerable areas."

"Currently, no advisory for small craft is issued as conditions are below threshold. However, poor visibility and gusty condition will be the main concern for all mariners.”

The public has urged to continue to monitor latest weather forecasts as well as warnings as Samoa enters its annual tropical cyclone season.

According to the severe weather information issued by the S.M.S. on Monday evening, heavy rain warning and flood advisory was issued for all of Samoa.

"The latest satellite images this afternoon show a broad cloud band that is associated with a low-level circulation center to the west of Savai’i Island.

"This system will continue to affect the islands with heavy downpours as well as gusty winds at times for tonight. These conditions are expected to ease by tomorrow."

Potential impact include heavy downpours with poor visibility, gusty winds, foggy and slippery roads over mountain passes and ranges, pooling near roadsides and waterways, and possible flooding.
