Heavy rain warning issued

The Samoa Meteorology Division has issued a heavy rain warning and flood advisory for all of Samoa.

In a Public Severe Weather Information issued by the Samoa Meteorology Division on Wednesday evening, they warned of heavy rain.

According to the notice, an area of cloud development remains within the vicinity of Samoa due to an active convergence analyzed on Wednesday afternoon. 

Brief heavy falls and thunderstorms with gusty wind conditions impacted highlands and some parts of the country earlier in the day as the result of the weather system. 

The system was expected to intensify rain and gusty wind conditions by Wednesday evening in to Thursday across the island.

Potential impacts of the weather include heavy downpours with poor visibility, gusty winds, foggy and slippery roads over mountain passes and ranges, pooling near roadsides and waterways.

Other impacts of the weather system include river overflows and landslides.

The current weather follows a few days of thunderstorms which was a result of a perfect combination of ingredients of wild weather.

The heavy rain in recent days had been accompanied by bursts of thunder and lightning, including a loud thunderclap that could clearly be heard at 5pm on Monday. 

According to the Samoa Meterology Service’s Forecast Discussion, unsettled weather conditions associated with the South Pacific Convergence Zone (S.P.C.Z.) will remain nearly stationary over Samoa until Friday.

A Forecast reveals that these conditions will maintain wet and gusty periods on land areas and marine waters, and that global models predicted a ridge of high-pressure system to reinforce from the southeast, it will likely push the S.P.C.Z. away to the Southeast and allow easing weather conditions in the latter part of the week.
