The Samoa Meteorology Division has issued a heavy rain advisory for all of Samoa, which has been triggered by a convergence zone that remains within the vicinity of the country.

The Meteorology Division issued the advisory 5pm on Tuesday [Samoa local time] and forecast that the weather system is likely to introduce moderate to heavy falls at times with fresh and gusty winds.

The potential impact includes heavy downpours with poor visibility and slippery roads, gusty winds at times. 

A small crafts advisory has also been issued by the Meteorology Division for all coastal to open waters of Samoa.

The Meteorology Division’s Principal Scientific Officer, Silipa Mulitalo, told the Samoa Observer that the convergence zone has triggered the rainfall advisory. 

"We have a rainfall advisory for Samoa due to a surface convergence moving over the islands from the south, and migrating to the north." 

According to Mr Mulitalo, scattered rainfall is likely on Tuesday night and Wednesday, before the convergence zone moves completely north Wednesday evening.

"From tomorrow onwards until next week, showers of rain will be concentrated to southern districts, eastern districts, and highlands, and possibly heavy at times due to the exposure of those locations to the prevailing southeast wind," he said.

Mr. Mulitalo also advised that winds are expected to strengthen further at the weekend.

"We are expecting fresh to strong winds by Friday and accompanied by the buildup of waves and high swells for the coastal and open waters. Hence, the small craft advisory will remain unless the meteorological observations drop below our threshold values," he added.
