A heavy rain advisory previously in force for all of Samoa was cancelled late on Monday afternoon by the Samoa Meteorology Division.

The most recent weather advisory from the MET Office said new satellite imagery had shown that major convections have shifted further away to the south from the islands. 

"Meanwhile, a moist northeasterly wind-flow remains persistent," the notice reads.

"[It had] caused brief heavy falls on highlands this afternoon.

"[The] current situation may provide partly cloudy skies with brief isolated showers over the country."

Partly cloudy weather with brief isolated showers starting from Monday night is forecast by the bureau.

For Tuesday and Wednesday, both Upolu and Savai'i are forecast to enjoy mostly fine weather with the exception of some brief showers in certain areas. 

The country's marine forecast shows a northeast-to-easterly wind flow prevailing over coastal to open waters.
