Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...High pressure centered over Bermuda extends a ridge to south Florida.

NE to E winds will pulse to gale-force nightly offshore Colombia through at least Fri night. Winds and seas will begin to gradually diminish Sun through Mon as Atlantic high pressure retreats to the NE. NW Caribbean W of 85W .TODAY...E winds 10 to 20 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A central Atlantic trough is nearly stationary along 59W-60W from 20N to beyond 31N. 1025 mb high pressure centered over Bermuda extends a ridge SW to south Florida. The ridge will begin to shift S today and allow a cold front to sink SE into the NW waters this morning. The front is expected to stall along 29N early Fri then drift N into the weekend to the W of 68W, while moving slowly SE across the waters E of 68W. Strong high pressure N of the front will induce freshening trade winds south of the front and strong NE to E winds across the NE waters Fri night through Sun morning, before diminishing.
