SUNDAY 26th MAY 2019 (AM SHIFT)
A light southerly wind-flow continues to persist over the island. Stable and drier weather condition with few low –level clouds will impact the island within the now-cast period. A low-pressure system to the southeast will sink southeast but the elongated trough to remain nearly stationary to the south of the forecast zone. No major event forecast for today. Therefore, expect stable conditions with cloud development will increase relying on the surface heating in the afternoon.
MONDAY TOWARDS FRIDAY:
Cool and dry Southerly wind flow will provide stable weather conditions in the next 2 days. Winds will swerve more Easterly by Monday due to an intense high-pressure system to the East of New Zealand ridging over the Islands. Apart from trade-wind weather, a speed convergence along the ridge will bring winds of more than 20 knots for Southern coastal waters and some rainfall activities by Tuesday. The tradewinds will be the main weather feature for the latter part of the outlook period as the high-pressure system migrates slowly Eastward.
MARINE OBSERVATION & OUTLOOK:
Observation shows waves within the range of 1.5-2 metres. Waves and swells may pick up by Monday when the trade-wind increases in strength. A small craft advisory is likely for the beginning of the new week.
