A reinforcing cold front extends from 31N75W to West Palm Beach, Florida. As the reinforcing front accelerates eastward across the western Atlantic, the two fronts will combine by this evening from 31N64W to eastern Cuba. The merged front will reach from 31N59W to the Windward Passage early Wed, and from 31N50W to the Mona Passage early Thu as the southern portion becomes nearly stationary. Strong to near gale force SW winds are occurring E of the initial cold front, mainly N of 28N. Strong to near gale force NW to N winds are developing early this morning behind the reinforcing cold front. A period of NW to N gales is expected N of 29N, to the SW of Bermuda, late this morning through this evening. In the wake of the front, high pressure will build in off the coast of Georgia and northern Florida on Thu. The next cold front is likely to bring fresh winds Fri and Fri night to waters north of 29N. ATLC waters from 27N to 31N W of 77W .TODAY...N winds 20 to 25 kt.
