SYNOPTIC DISCUSSION
WEDNESDAY 17th JULY 2024 – A.M SHIFT

TODAY:
Scattered low – mid-level clouds stream over the islands along the southeasterly wind flow as indicated by the satellite data this morning. The intense high-pressure system further south has continued controlling our weather for the last few days. Which provides stable and dry conditions over the country. The sounding profile reflects such dryness of the atmosphere with indices indicating unfavourable conditions for shower development over the group. therefore, anticipates partly cloudy weather apart from a few showers.

THURSDAY THROUGH TUESDAY:
A surface high pressure well to the southwest will migrate eastward and continue to drive a gentle easterly breeze across Samoa through Wednesday. A weak surface trough moving from the southwest will keep moisture nearby but cloud development will be suppressed by the mid-level high pressure over the region through this timeframe. By Friday evening, scattered showers will return as a short-wave trough enters the area from the east. A gentle easterly breeze will become northeasterly on Thursday. Scattered showers and isolated thunderstorms will enter the region by early Saturday morning. The high pressure will dominate the region starting by Sunday and bring a moderate easterly breeze.


MARINE OUTLOOK:
Wave activities remain below the advisory threshold and predictions indicate such activities to remain as so till Wednesday of next week. The strengthening of the high-pressure system is likely to enable wave activities reaching at least 2.5 metres no more than 3 metres. Thus, may warrant the activation of a Marin Advisory for all marine waters of the island group, although for now, activities remain well below the advisory threshold.


ADVISORY/WARNING:
NONE
