.SYNOPSIS...

Low pressure offshore is producing choppy seas and gusty winds.
The latest ASCAT pass shows winds around 20 to 25 knots in the
outer coastal waters with waves between 4 and 6 feet. Through the
night conditions will worsen as the low deepens and moves closer
to the Louisiana shore. With waves building another 1 to 2 feet.
Widespread showers and thunderstorms will continue through the
night and into Sunday.

By Sunday evening the low will be moving towards Florida and
conditions will improve. To start the week, we will see steady
onshore flow around 5 to 10 knots with combined seas less than 4
feet.
