Sunday 25th June 2017 PM.

  Tonight and tomorrow:

   A broad area of high pressure system continues to prevail over Samoa, maintaining east to southeast wind-flow. Latest satellite loops shows scattered low-level clouds streaming westward which also ride along the easterly flow. Gentle to Moderate east to southeast winds was observed hourly across the Samoan island chain from manual and automatic weather stations , and it was also supported by the ASCAT pass and radar wind-profiler this afternoon. Global models suggested a minimum showery activities with gentle trade-wind flow to persist over Samoa within the now-cast period.

 

Tuesday through Thursday:

A convergence zone ridging along/ ahead of an intense high pressure system building from far southwest continues to move slowly near the island by Tuesday, thus provide wet and unstable weather condition for the group within mid-week . Behind the convergence zone the trades will kick-in again due to the aforementioned high pressure system. Therefore, expect an increase with the moisture content near the surface within mid-week before drier condition move over later in the week.


T
rade-wind swells continues to subside below the advisory threshold as shows by the Aunuú bouy observation of 5-7feet this afternoon . Wave-watch model predicted this swells to remain below the advisory threshold through the outlook period. Therefore, our valid small craft advisory is now cancelled for all of Samoa coastal water.

Small craft advisory cancelled
