The trough that brought showers and thunderstorms over the weekend
continues to weaken across the area. The latest satellite and
upper sounding reflects a dry and stable pattern as thunderstorms
are focused northwest and northeast of the territory. Nonetheless,
numerous showers are forecast for tonight before becoming
scattered on Monday, as long as the trough remains in the area.

Easterly winds of 10 to 15 mph will persist through Tuesday before
diminishing to a gentle breeze Tuesday afternoon as the ridge to
the south continues to recede from the area. Light and variable
winds will prevail through the end of the week. However, passing
showers will remain possible due to wind convergence and
land/sea-breeze effects throughout the week.

Choppy seas and high surf are evident as swells continue to move
through the area. Expect seas to remain within advisory thresholds
until Monday night (7 to 9 feet), before gradually diminishing on
Tuesday. Although improved ocean conditions are expected Tuesday,
there may be a delay in lower wave heights until later in the
afternoon (account for uncertainty in model data). However, ocean
conditions are expected to be ideal Wednesday through the weekend.

Even with calmer conditions, model data indicates a southeast
swell moving in the area by midweek. This suggests longer gaps
between waves, which are typically ideal for mariners in open
waters, though some uncertainty remains. Nonetheless, calm winds
and lower wave heights forecast from midweek into the weekend
suggest generally favorable conditions for the Fautasi Race. We
will continue to monitor trends in case ocean conditions change.
