.Synopsis for Marianas Waters...Altimetry and buoys are showing
combined seas of 5 to 7 feet this evening. Seas are expected to
slowly build through Friday as a long-period north swell moves
through the region, with seas expected to peak around 9 feet, just
below hazardous levels for small craft. An approaching shear line
will start to move into the Marianas this weekend, increasing the
potential for showers. Winds and seas may also start to build, but
the exact extent and timing will depend on how far the shear line
will push south.
