Light to moderate onshore flow will continue through Friday, along
with occasional shower activity as a coastal low moves across the
northwestern Gulf Coast. Late Friday, a strong cold front will push
through the coastal waters with strong offshore flow developing
behind it Saturday and Sunday. Small Craft Advisory conditions are
expected from late Fri/early Sat through early Monday as the
pressure gradient remains tight overhead. In addition, light rain
will also be possible over the coastal waters through the weekend.
