FORECAST DISCUSSION

SUNDAY 24TH March 2019, AM SHIFT

TODAY AND TONIGHT:

An intense high pressure system ridging from far southwest maintains moderate south-easterly wind-flow over Samoa. The atmosphere remains stable while moisture exist near the surface, thermal mechanism was to trigger showers for afternoon which will later clear in the evening. Showers to venture over Samoa’s forecast zone due to the dominating trades.

MONDAY TOWARDS SATURDAY:

By Tuesday winds may swerve more northeast and may generate brief showers across the country. During this time there is potential low development near Fiji islands as highlighted by severe weather guidance as an area for heavy rain. Coincidently, an intense high pressure near NZ will be at its peak by then and feeding into the low level circulation, and forcing a north-easterly wind regime for Samoa.

MARINE OUTLOOK:

Current observations from Aunu’u buoy indicate waves below 7ft thus nil advisory is still valid at this stage.

WARNING/ADVISORY:

NIL
