.Short term...
Light winds and scattered showers remain as a ridge of high
pressure lingers across the region. Although stable weather
is expected with a high pressure system, latest satellite data
shows convective clouds scattered across the area. Sounding data
also depicts an unstable and moist profile, which is likely due
to warm temperatures and high precipitable water amounts seen on
MIMIC-TPW. Scattered showers, possibly numerous at times with
light winds will hold through Monday.

.Long term...
The high pressure will strengthen on Tuesday minimizing showers
development in the area through the end of the week. Light winds
and scattered showers will persist for the rest of the forecast
period.

&&

.Marine...
Latest observations from the PacIOOS buoys show seas around 4 to
6 feet. Light winds keep a calm ocean surface, however, a south
swell may generate strong rip currents near-shore. Beachgoers are
encouraged to swim with caution, especially in villages where rip
currents are noticeably strong.

Swells are forecast to subside by Tuesday and ocean conditions
will remain calm through Thursday. By the weekend, storms
developing to the north could elevate wave heights up to 9 feet or
higher.
