Synopsis for the the SW N ATLC including the Bahamas .SYNOPSIS...A stationary front extends from 30N65W to a 1010 mb low pressure centered near 28N72.5W then continues as a cold front to central Cuba near 22N78W.

As the low shifts NE over the next 24 hours, it will drag the cold front to 30N65W to another 1011 mb low pressure near 28N70W to 23N78W by Thu morning. A reinforcing cold front will merge with the stationary front on Fri, and extend from 28N65W to eastern Cuba.
