SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS

.SYNOPSIS...A stationary front enters the area near 27N65W, then
continues westward to the NW Bahamas. A warm front extends from
the NW Bahamas to a 1014 mb low pressure located over the State
of Georgia. Scattered showers and tstms are associated with the
warm front affecting the waters N of 27N. The warm front will
continue to lift northward, with strong to near gale force
southeast flow developing across the forecast waters north of
the Bahamas this afternoon and tonight, in association with the
surface low forecast to move eastward into the Atlantic Ocean on
Tue. It will push a weak cold front across the northwest portion
Tue through Wed, and across the north-central waters Wed night
and Thu while it slows down. Another weak cold front will move
over the far northwest portion Wed night and Thu before it also
slows down Thu night and Fri.
