Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Intensifying low pressure over the western Atlantic has weakened the pressure gradient across the Caribbean Sea. As a result, mainly fresh to occasionally strong trade winds will prevail near the coast of Colombia this week. Moderate to fresh trades along with persistent NE to E swell will continue to impact the waters east of the Lesser Antilles for the next several days.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A stationary front extends from a 1013 mb low near 31N76W to the NW Bahamas and Straits of Florida. The low is producing gale force winds and building seas mainly N of 31N. The low will track NE today, with the associated cold front reaching from near 31N72W to the central Bahamas and to central Cuba this afternoon and from near 31N69W to 27N72W and to eastern Cuba early tonight. Gale force winds west of the front to 75W and N of 30N will shift NE of the area this afternoon. Strong high pressure will build across the western Atlantic in the wake of the front, with the pressure gradient between it and a weakening cold front that will move S into the area leading to fresh to strong easterly winds over most of the forecast waters by this weekend. Seas will build E of the Bahamas on Sat with the increasing easterly flow. ATLC waters from 27N to 31N W of 77W .TODAY...N winds 10 to 15 kt. Seas 6 to 9 ft. .TONIGHT...NE winds 10 kt.
