The Samoa Meteorology Office says that isolated showers, heavy rainfall and thunderstorms will continue on Tuesday, while a flood warning will remain in effect for the duration of the day. 

The cause of recent poor weather is an active convergence zone in the vicinity of Samoa, but in a statement on Monday forecasters said that while the weather system was dissipating it still promised to bring inclement weather overnight and into Tuesday. 

"[The] remnant of the convergence zone continues to remain within the vicinity of Samoa with associated intermittent showers," the Meteorology Office said on Monday evening. 

"However, the main cloud band of the convergence zone is now displaced further southwest of the island. This convergence zone is expected to dissipate later tonight as it moves further southwest. 

"Therefore, expect isolated showers to become scattered at times with heavy fall and thunderstorms."

The potential impacts of the weather system include poor visibility; foggy and slippery roads over mountain ranges; and water pooling near waterways and roads. 

Forecasters are predicting a wet week ahead. Isolated rainfall and possibly heavy showers are predicted for tomorrow. Wednesday and Friday are also expected to have overcast conditions and isolated showers.

Thursday is projected to have the most pleasant weather this week with mostly fine conditions but still with brief showers, according to predictions issued on Monday.
