.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
Weak to moderate onshore flow will continue today through Tuesday.
Moisture will increase today due to an upper level trough,
providing isolated to scattered showers and thunderstorms.
A weak onshore flow will persist through the middle part of the
week then becoming weak to moderate toward the weekend. Rain
chances will begin to increase by the end of the work week as the

remnants of Harvey will be during the week, mariners are advised
to follow the latest forecasts.
