A mid-level high pressure system continues fair weather for the territory. This is evident on latest satellite and surface observations showing sunny and partly cloudy skies. Expect stable conditions to remain through Sunday becoming slightly unstable on Monday. A strong high pressure system extending from the southwest is forecast to converge with current east winds. This wind convergence will create a slight lifting mechanism for shower development embedded within the trade wind flow. Expect scattered showers through midweek, increasing to numerous showers by the end of the week as a trough moves in the area. Breezy winds will hold for the rest of the forecast period. && .Marine... Calm ocean conditions remain for the territory as no significant swells or winds are observed in the area.
