This activity is capable of producing strong gusty winds and frequent lightning as it quickly moves eastward through Mon ahead of the next cold front. This next cold front will emerge off the Georgia and NE Florida coasts late tonight into early Mon. The front will reach from near 31N79W to West Palm Beach early Mon afternoon, from near 31N75W to NW Cuba Mon evening, from near 31N67W to 26N70W to eastern Cuba early on Tue before stalling from near 27N65W to central Cuba Tue night. The cold front will gradually weaken through Thu as high pres builds eastward over the area. Minimal to strong gale force winds are expected over some areas both ahead and behind the front Mon through early Tue afternoon. In the wake of the front, relatively weak high pres will build W to E along 27N through early Wed as yet another strong cold front begins to advance across the NW waters of the basin. This front will be preceded by fresh to strong southwest winds and mostly strong W to NW winds to the N of 27N as it quickly moves across the forecast waters to just east of the basin early on Thu. High pres will build from W to E across the central waters in the wake of the front. ...GALE WARNING N OF 30N E OF 79W... .TONIGHT...S to SW winds 10 to 15 kt S of 27N, and S to SW 15 to 20 kt N of 27N.
