   AMZ001-130300-  Synopsis for Caribbean Sea, and Tropical N Atlantic from 07N to  19N W of 55W  1054 AM EDT Wed Aug 12 2026      .SYNOPSIS...The pressure gradient between the Atlantic ridge and  the Colombian Low will continue to support fresh to strong trades  over the south-central Caribbean through tonight. The ridge will  begin to strengthen modestly behind a tropical wave currently  moving across the eastern Caribbean by night, leading to a  significant expansion in coverage of strong trade winds over the  central and eastern portions of the basin through Sat. Winds may  increase to gale-force offshore of Colombia Fri night and Sat night.  Looking ahead, an area of showers and thunderstorms associated  with a tropical wave is located about 900 miles west-southwest of  the Cabo Verde Islands. Environmental conditions are forecast to  be conducive for development during the next couple of days, and a  tropical depression will likely form while the system moves westward  to west-northwestward across the central tropical Atlantic.    $$
