.DISCUSSION...
Upper air observations (RAOB) from this afternoon together with
the latest satellite imageries show dry conditions with light and
variable winds remaining over the area. Model data show these
fair weather patterns remaining for tonight and Tuesday. By late
Tuesday, trade winds will increase to a fresh breeze with embedded
showers. This pattern will continue for the rest of the week.
Showers will remain in the passing form, brief and heavy at times
but not flash flooding. As trades increase further to near gale
force strength, it will help hold a trough to the north of the
area.
However, model data shows a possible low pressure system moving
just south of the area, pulling the aforementioned trough over the
area, increasing the potential for showers by the end of the
forecast period. Will continue to monitor these conditions as the
week progresses. In the meantime, expect strong gusty winds with
embedded showers for the rest of the week.

.Marine...
Favorable conditions are expected to remain across the coastal
waters through at least Tuesday. By late Tuesday, model data shows
a large south swell moving into the area and is expected to build
to warning levels by Wednesday through Friday. Strong trades
nearing gale force strength with higher gusts will likely generate
hazardous seas, surfs, and deadly rip currents for this time
frame. These conditions will prompt alerts as more data becomes
available.
