Synopsis for the the SW N ATLC including the Bahamas .SYNOPSIS...A cold front reaching from 1015 mb low pressure near 30N65W to Hispaniola near 19N70W will gradually stall and weaken through tonight as the low pressure continues to move northeast of the area, allowing winds and seas to diminish accordingly. High pressure will build off the U.S. east coast in the wake of the low through Sun, then continue E ahead of the next cold front expected to move off the NE Florida coast by Sun night. A low pressure is forecast to develop along the frontal boundary near 30N77W by Mon night. Gale conditions could be possible across the north waters between the low and high pressure over the Carolinas Mon night, and again Tue night as the low pressure deepens just N of area.
