SYNOPTIC DISCUSSION
SATURDAY 27th JULY 2024 – AM SHIFT

TODAY:
The moist northerly wind flow prevails over Samoa. Meanwhile, the convergence zone to the South lies slow moving over the group. The system is introducing isolated to scattered showers with brief heavy falls in some areas, and thunderstorms with gusty winds at times. Hence, the Heavy Rain Advisory remain in force for all areas of Samoa.

SUNDAY THROUGH THURSDAY:
The low-pressure system located to the southeast of the Fiji group is expected to move eastward. This shift will result in the trough axis moving towards the area by Sunday with rainfall activities and variable winds. By the beginning of next week, the Trades are forecasted to return as a high-pressure system in the Tasman Sea advances, pushing the trough northward and away from the group.

MARINE OUTLOOK:
The high-pressure system centred further southeast continues moving eastward in abating formation and thusly aids the recession of wave activities below the advisory threshold of 2.5 metres. This situation warrants the cancellation of the previously enforced marine advisory for all marine waters of Samoa.

However, another surge of high swells and fresh southeast winds are expected to enter the marine waters of Samoa by Tuesday next week as the high-pressure system in the Tasman Sea migrates eastward, and will likely re-issue this Advisory if conditions persist.

ADVISORY/WARNING:
VALID: HEAVY RAIN ADVISORY

CANCELLED: MARINE ADVISORY
