Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...Strong high pressure N of the area will support a large area of strong to near-gale force trade winds across the central and portions of the SW Caribbean Sea through the forecast period. Fresh to strong trades in the E Caribbean will diminish to moderate to fresh today before resuming by Tue night as a low pressure develops over the central subtropical Atlantic waters. Fresh to strong winds in the E basin will then continue through Thu. Looking ahead, the next cold front will enter the NW Caribbean early Mon, followed by fresh N to NE winds with seas building to 11 ft in the Yucatan Channel. The front will stall over the NW Caribbean early in the week before retreating back north of the basin as a warm front by mid-week.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weakening stationary front extends from near 20N55W to Hispaniola adjacent waters. The pressure gradient between strong high pressure N of 30N and lower pressure associated with the dissipating front will continue to produce fresh to strong NE to E trade winds south of 24N through tonight. Later this morning, fresh to strong southerly flow will set up over the waters E of NE Florida to about 70W in advance of the next cold front. This cold front is expected to move into the NW forecast waters this evening. Strong to near-gale force winds are likely on both sides of the front, with brief gales possible tonight N of 29N between NE Florida and 73W. Seas will build ahead and behind the cold front. The front is forecast to stall late Mon night from Bermuda to central Cuba. By mid-week, the front is expected to lift N as a warm front. The pressure gradient between very strong high pressure north of the area and lower pressure associated with the warm front may induce gales to gust fprce NE to E winds and building seas to the east of Florida by mid-week.
