The high pressure system that holds breezy weather over the Islands will continue to produce southeast trades through the new week. Meanwhile, latest satellite loops shows a trough to the north edging close the territory. It seems model data struggles with the strength of the high pressure system as it was anticipated to move farther east Monday. However, it is now expected to linger just southeast through midweek leaving the Samoa Island chain at the boundary between the trough and the high pressure system. This means showers could be heavy at times with the trough and breezy with the high pressure system. All in all, the trend for showers is still forecast to increase Sunday Morning and remain at numerous rain through at least midweek. The potential for flooding however, is not as evident today for the forecast period. Moisture and instability will finally decrease Thursday through the end of the week as the trough weakens in the area. .Marine...
