.DISCUSSION...
The latest satellite imageries shows open cell cumuli clouds
streaming across the islands throughout the day. This phenomena
will remain through at least midweek. However, model data shows an
increased potential for showers tonight through the early morning
hours. This is due to a trough to the south edging closer to the
territory. By early Tuesday morning, the trough will likely
migrate east-southeast as the high pressure system to the
southwest pushes it eastward. Also, the gentle to moderate
easterly flow will remain throughout the week. Therefore, expect
scattered to numerous showers with a gentle breeze for tonight
decreasing to isolated showers Tuesday through the rest of the
short term forcast period.

By the second half of the week, the aforementioned high pressure
system will be exiting to the east while producing a consistent
gentle to moderate east wind flow. This consistent wind flow will
have embedded showers, which may be heavy at times. Expect
scattered to numerous showers with a moderate east flow for the
rest of the forecast period.

.Marine...
Seas have been gradually trending downward through the last couple
of hours. Model data together with manual observations of seas
have subsided to 4 to 6 feet throughout the day and will remain
through at least Wednesday night. Model solutions are also showing
seas building to 5 to 7 feet on Thursday and remaining through
the rest of the forecast period. Seas building in the latter part
of the week coincides with the consistent moderate easterlies for
this time frame. Will continue to monitor the latter part of the
week as more data becomes available.
