Island TX out 60 nautical miles including Sabine and

.SYNOPSIS...
Breezy offshore winds will continue to create hazardous conditions
for small craft through this morning. Winds will rapidly decrease
during the morning as the front continues to move south and
weaken. Rough seas will continue with the strong winds with
altimeter showing maximum wave heights around 7 feet. By this 
afternoon, winds will decrease rapidly, staying offshore, but 
weakening down to 10 knots. Waves will also decrease with the maximum wave
heights dropping down to around 4 feet.

Based on the current wind direction, a low water advisory is
unlikely, but water levels will be monitored until winds weaken.

Starting tonight, winds will shift, becoming onshore but remaining
light through the rest of the week.
