The Samoa Meteorology Service (M.E.T.) has issued a heavy rainfall warning as well as a flood advisory for all of Samoa. 

An M.E.T. spokesperson told Samoa Observer that there is an active convergence zone north of Samoa, which is triggering scattered to widespread rain, which will continue to impact the country on Sunday night and into Monday. 

Isolated thunderstorms are also possible with heavy falls and gusty winds at times, according to the spokesperson.

"The convergence zone has moved up north of Samoa but a trough of low pressure is on Samoa, hence why we had rainfall and scattered widespread rain will impact from tonight (Sunday night) until tomorrow (Monday). Isolated thunderstorms are possible with heavy falls and gusty winds," he said.

The convergence zone is within the vicinity of the country, the spokesperson added, consequently the heavy rain warning will remain in effect for all of Samoa.

"The only warning that is in effect for Samoa is the heavy rainfall and flooding warning, but because these rainfall will trigger flooding advisory effective now. However, we will be monitoring the trough of low pressure that's currently on Samoa right now," he added.

While there is a chance of a cyclone developing due to the low pressure systems, the spokesperson indicated that the country is not vulnerable at the moment to the extreme weather condition.

"Samoa will be facing only heavy rainfalls and the potential impact of the forecasted heavy downpour will include poor visibility and foggy and slippery roads over mountain passes and ranges. There will also be gusty winds at times causing roadside pooling."
