THURSDAY 25th APRIL 2019 PM SHIFT
TONIGHT & TOMORROW:
Massive amount of moisture located just Southeast of Manu’a Is towards the Southern Cooks whereas dry surge aloft approaching the island from the western side. A developing ridge of high pressure system from the Northeast continues to push activities associated with a trough further south and directed Northeasterly wind-flow over the group. A warm air advection suppresses the development of any major activities within the now-cat period. Models predicted fine spell for tonight heading to tomorrow including the wind change to the easterly when the ridge of high pressure system fully take control of our weather condition.
SATURDAY TOWARDS TUESDAY:
Stable and drier weather condition will persist over the island within the outlook period due to an active ridge of high pressure system develop from far south. Gentle to moderate trade-wind flow with minimum rainfall activities expect for the island heading to the weekend and the start of the new week. The trough of low pressure system extends from Solomon to Southern Cooks Is with an embedded developing low pressure system near Fiji Is.
