SYNOPTIC DISCUSSION
FRIDAY 04TH OCTOBER 2024 – P.M. SHIFT

TONIGHT:
Fresh southeasterly wind continues to persist over Samoa with scattered low-level due to a high-pressure system situated far south of the island. A dry atmosphere and subsidence inversion layer near the surface suppress the development of major convection in the afternoon. Models suggest limited rainfall activity aside from brief showers driven by the trade-wind flow. Therefore, expect partly cloudy with brief showers and fresh southeasterly wind across the island.

SATURDAY THROUGH THURSDAY:
Southeasterly winds will persist across Samoa from tomorrow through the weekend, with an expected increase in wind strength. As a result, a Wind Advisory may be issued for the public and marine areas. Meanwhile, a convergence zone is forecast to approach the islands from the northeast by Monday, bringing periods of gusty winds and increased showers. Weather models predict rainfall associated with this system, and a Heavy Rain Advisory may also be issued. We will continue to monitor updates closely and provide further advisories if any significant weather changes occur.

MARINE OUTLOOK:
A strong high-pressure system located East of New Zealand continues to generate moderate to fresh southeast winds across Samoa, along with waves and swells of 2.5 to 3 meters. These conditions are expected to affect the marine areas of the islands tonight and through the weekend, with gusty southeast winds at times. Therefore, the Marine Advisory remains in effect for all of Samoa's marine waters.
