The front will reach the southeastern Gulf waters Wed and the Straits of Florida by Wed evening. In the wake of the front, strong northerly winds are expected in the western half of the basin, with gale force winds expected west of 95W on Tue. A secondary front will drop southward to the northern Gulf early on Fri and reach the far southwestern Gulf by Fri evening. Strong high pressure will build in behind this front. The pressure gradient between the front and broad low pressure that is expected to form over the western Caribbean by the end of the week is expected to freshen the northeast winds over most of the southeastern Gulf by the end of the week. These winds may reach strong speeds on Sat and Sat night along with building seas. $$ GMZ011-290915- NW Gulf including Stetson Bank- 501 PM EDT Mon Sep 28 2020 .TONIGHT...N to NE winds 20 to 25 kt.
