DISCUSSION

Partly sunny skies with moderate south winds continue to remain across the islands throughout the day. The latest satellite imageries show a low pressure system to the southeast with a trough attached. The trough is expected to continue to move away from the area as the aforementioned low pressure pulls it away. Also, a high pressure system to the south will continue to migrate east as it pushes the trough further north and east of the area. Showers embedded within the south wind flow will move across the area from time to time, bringing scattered showers for the weekend. Flash flooding conditions are not expected for this forecast period.

Long term model projections has the high pressure system migrating further east as winds turn east-southeast on Monday through the rest of the forecast period. Expect gentle to moderate east- southeast winds with scattered showers for the new week.

Marine

As the aforementioned high pressure system to the south continues to produce moderate to fresh south winds, seas will also build to hazardous conditions. Model data show seas gradually building to advisory thresholds throughout the day and remain through at least Sunday night. By late Sunday into Monday, seas and winds will subside to more favorable levels. Thus, advisories for small crafts and high surfs are now in effect through at least Sunday night. The threat of elevated seas, dangerous surfs and strong rip currents will impact south shores tonight through Sunday night. No other swell is expected for the rest of the forecast period.
