Island TX out 60 nautical miles including Sabine and

GMZ400-142100-
345 AM CDT Wed May 14 2025

.SYNOPSIS...
A weak shortwave moving near the region will tighten the gradient
against high pressure in the north Gulf, resulting in breezy
onshore flow around 20 knots gusting to 30 knots through this
afternoon. Another round of elevated winds are expected during the
day Thursday. Long southerly fetch in the west Gulf will keep
elevated seas in the forecast through Thursday as well. Thus,
Small Craft Advisory conditions are expected to continue.
Otherwise, ridging remains in control and no rain is expected
through the forecast period.
