Heavy rain advisory remains for Samoa
A heavy rain and flood advisory remain in effect for Samoa.
That's according to the Public and Severe Weather Information issued by the Samoa Meteorology Division on Sunday evening.
It says the convergence zone, responsible for flooding last Friday, continues to bring associated cloud band and isolated showers with possible brief heavy falls and few thunderstorms.
“The aforementioned system will remain nearly stationary for the next few days. Waves and swells remain above the advisory threshold of 2.5-3 meters. Therefore, all advisories remain valid for all of Samoa.”
The Samoa Meteorology Division explains that potential impacts of the weather include heavy downpours at times with poor visibility, foggy and slippery roads over mountain passes and ranges, pooling near roadsides and waterways, and rough seas is also expected.
For Monday through Saturday, the Forecast Discussion explains that the ridge of high pressure to the North predicted to maintain
“Northerly wind flow throughout the long term forecast, keeping the SPCZ to the South of the forecast zone. However, a weak trough along the Northerly flow may provide isolated showers by mid-week and is forecast to linger south of the group in the latter part of the outlook period with showery activities.”
“By Thursday, a low circulation may develop over Niue and move Eastward. This situation will redirect the aforementioned trough over the Islands towards the end of the week.”
