.Synopsis for Marianas Waters...Local buoys shows combined seas
around 5 to 7 feet across the area. Recent altimetry data shows
higher seas of around 6 to 8 feet east of the Marianas. Gentle to
moderate winds will prevail through the rest of the week, becoming
fresh at times this weekend as a trade-wind surge builds westward
into the region. This will increase seas by a foot or so come
Sunday due to a larger incoming trade swell. A trough will move
through the region Friday and Saturday.
