Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A small area of low pressure located about 130 nm E
of the northernmost Bahamas continues to produce disorganized
shower and thunderstorm activity. While environmental conditions
are only marginally conducive due to nearby dry air, further
development of this system could lead to the development of a
tropical depression while the low moves W-NW and approaches the
NE coast of Florida or the Georgia coast early on Friday.
Regardless of development, fresh to strong NE to E winds and
rough seas will prevail across the waters N of 28N through early
Fri. Afterward, high pressure will build in the wake of the low,
supporting gentle to moderate winds through Mon night. Otherise,
moderate to fresh E winds are forecast for Hispaniola adjacent
waters, the approaches to the Windward Passage and the Great
Bahama Bank this evening through Sat night.
