nautical miles including Galveston and Matagorda Bays

.SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM...
High pressure will help keep light winds in place tonight. As the
surface pressure gradient tightens with high pressure departing
to the east on Saturday, winds and seas will increase. Caution
flags or advisories may be needed by saturday evening. We are
continuing to monitor for possible sea fog development early next
week along with the potential for elevated swells given the
forecast of a lengthening SE fetch. A cold front will cross SE
Texas on late Tuesday or early Wednesday. While the timing of this
feature is still uncertain, showers and thunderstorms may develop
along and ahead of the advancing front.
