SYNOPTIC DISCUSSION

SUNDAY 19THJANUARY 2024 AM SHIFT.

TODAY:

The Easterlies remain persistent over Samoa, such avails cloud accumulation over wind ward areas – the atmosphere remain stable and dry, whereas rainfall remain solely on solar radiation, resulting to localised convections triggered by the topography of Samoa. Therefore, anticipate partly cloudy periods with brief isolated showers and a few thunderstorms.

MONDAYTHROUGH FRIDAY:

On Monday, another weak trough of low pressure moves from the North, which could provide showers and thundery activities till Tuesday. Afterwards, the winds will veer easterlies this will bring trade wind showers. What’s more, a upper level ridge of high pressure which generate dry and cold southerly winds. Furthermore,thewind shear environment is expected to strong thus hindering convective clouds formation throughout the outlook period.

MARINE OUTLOOK:

As of now, the current Altimetric readings with both the Aunu’u and King-Poloa data generally indicate the wave and swell heights is continuously below the 2.5 metre threshold posing no risk or threat to all marine waters of Samoa. Global wave model, currentlysuggest peak wave periods of more than 15 seconds on Sunday towards late Monday. However, there is a low chance of this predicted wave scenario could relatively generate significant wave heights above 2.5 metres. But, we’ll continuously update accordingly and inform ahead for major changes.
