60 NM including Sabine and Calcasieu Lakes and Vermilion Bay
336 AM CDT Mon Oct 25 2021

Good cold air advection over warmer Gulf waters, along with a
decent pressure gradient, will likely mean quite breezy conditions
with strong offshore flow and building seas on Thursday that will
linger into Saturday. Small Craft Advisories are a good bet
during that time frame.
